When Well Enough Can't Be Left Alone; A Backdate, EFI/ITB, AC Build with more...
 
This is going to be long, so if you want the TL;DR, jump to post #2

When I was a wee child my Swiss father introduced me to the 911 and let it be known that it was the car against which all other cars must be measured. This was completely unfair and also totally correct. We would read newsprint autotraders and circle potential cars on the weekends. Many times we went to look at 911s but none ever seemed to be right. Many years later my father happened upon a 911 that seemed to be the one, but he had to make a decision; he had just started flying sailplanes (motorless airplanes also known as gliders) and he couldn’t have both a 911 and a sailplane. He chose the sailplane. Somehow my mother was more ok with him being in an airplane without an engine than a sports car…

For years I would travel with him out to the airport and work on his planes; fabricating aluminum, carbon fiber and fiberglass parts in a seemingly never ending quest to extend the glide:sink ratio; the aviation equivalent of power:weight.

He unexpectedly passed away when I was 30 having never owned his dream car.

Throughout my life posters, Hotwheels, Testors models, Legos and various Porsche paraphernalia peppered my walls, dorms, apartments, offices and homes yet the real thing was ever elusive.

In the summer of 2020, deep into the pandemic I turned 40. And because a blowout party was verboten, my wife surprised me with a 930 rental for the day. A full tank of 93, a 917 key and nearly 1000 miles later the smoldering coals were now a raging inferno and within hours of returning the keys to the owner I was online scouring the car classifieds.

Two months later my 911 was en route.

They say never to meet your heroes for you will only be disappointed. Funny thing happed once I got the 911; it was kind of anticlimactic. Sure the first few months were a hoot and driving it was thrilling. But then the shine started to wear and it kind of became just a car.

That winter while avoiding work while reading some of the epic build threads on Pelican I decided that I’d try some minor mods.

Lots of CIS repair rebuilding got the engine working like butter. New headlights, fiberglass front and rear bumpers, and tons of other small mods had me feeling great.

And then I went to Checkeditout and realized that these cars are a dime a dozen and mine would never be a Singer, never be a RWB, never be concourse, never be anything all that different from every other 911.

So I started thinking about what made having this car fun and I realized that aside from the driving, it was all the wrenching I had been doing. One Saturday I took my 7 year old son to tinker on the car with me and it hit me like a ton of bricks; I was my father working on his plane, making it his, tweaking it and hot rodding it. It became clear in that moment while my kid was reading off WUR pressure numbers that I had to dive head first into this; I owed it to myself, my father and my son.

The TL;DR

I realized that simply owning a 911 was kind of anticlimactic; it’s the wrenching, tinkering and hot rodding that does it for me. My dad put that into my blood via his airplane and I want my kids to receive that same transfusion.

Fresh off he heels of my first rallye with FuelFed I drove the car to my workshop and proceeded to tear it apart.

Herein the process of not leaving well enough alone receives documentation.

I’ve given myself 7 Months to complete the following:

Backdating the car
X-Faktory EFI/ITB conversion
Classic Retrofit AC installation


I’ve bartered with my wife to get Saturday until lunchtime to work on the car. My alarm is set for 4:30am.

Showdown 11-15-2021 12:35 PM

Day 1

As soon as the engine was cool to the touch I jacked up the car and proceeded to take off the fiberglass bumpers I had installed last winter. On my modest 1977 S the weight reduction of 200 pounds by removing the old non-functional AC and impact bumpers made a world of difference but I knew almost instantly that the look was just a stopgap.

I cut out the rear reflector mounting panel and trimmed the front crush tube mounting brackets to make way for the new metal light boxes. I also mocked up the hood extension for the short hood and instantly knew that this was the right decision.

Having read a bajillion build threads of Pelican and Rennlist, having watched Ahh Garage Time and Home Built By Jeff to the point of memorization I felt confident in this first step. We’ll see how long that lasts.

Having only a half Saturday to work on the car gives me the total of about 2 full weeks (14 days) spread over the course of months to complete the projects. The only good thing about this is that I spend the week planning and choreographing my work so that when Saturday arrives I feel prepared.

Showdown 11-15-2021 12:47 PM

Day 2

The easy part of any project is the demo- tearing things off and ripping things out is fun and yields a great sense of forward momentum. So on day 2 of working on the car I decided to continue that feel good feeling and took more stuff out of the car.

After looking at the original wiring harness that was thoroughly “modified” by the PO when the Pertronix was installed I decided to scrap it and have Dennis (Timmy2) craft me a new CIS-less harness specific for my X-Faktory EFI/ITB setup. Al (X-Faktory) includes some of Dennis’ wiring harnesses for the injectors and comparing them to stock is like going to the Miss America Pageant with someone you met at the bar at last call….

On Dennis’ sage advice I took out the alternator and began preparing for the ClassicRetrofit Wosp alternator that comes with the kit. I’m not thinking about the AC install just yet but given how difficult it was to get the fan off I’m glad I did it now.

Out came the passenger seat and I started preparing for the ECU mounting. These comfort seats are HEAVY! Too bad adding lightness with seats is really expensive…

I installed some rivnuts (my new best friend) and then bolted the ECU to the floor with several rubber shock absorbers on each bolt to isolate the vibrations and keep the ECU off the floor. I thought about fabricating a panel but the fit is tight and I didn’t see it as necessary. Don’t’ worry, the raw metal was coated before the rivnuts.

I also drilled the necessary holes into the tunnel for the ECU harness and the MAP vacuum hose, which will be run next weekend, I hope.

http://forums.pelicanparts.com/uploa...1637012498.jpg

I also began fabricating the mounting panel for the fuel lines and vacuum manifold. The one that RHD supplies is like a wagon wheel and I wanted one that was linear allowing for a tidier install. Once it was painted I installed it loosely with rivnuts and fitted the pressure gauge and vacuum manifold. Unfortunately the MAP vacuum hose fitting, well, doesn’t so I will have to tap and thread the large plug on the right side of the manifold.

http://forums.pelicanparts.com/uploa...1637012566.jpg

http://forums.pelicanparts.com/uploa...1637012566.jpg

While still in the engine bay I started to run the fuel lines. Whenever I do any project be it housework or car work I like to play a game I call “How Many Trips” where I tabulate the number of trip to Lowes, Home Depot, AutoZone, Ace, etc… If it’s more than one I lose. I always lose. True to form I got tripped up without the necessary fittings so an order to Belmetric and the fuel lines will have to wait until next weekend. Ditto with the tapping of the manifold; nobody had a 1/8” NPT/NPS tap and I have Every. Other. Size…grr…

With the EFI/ITB work on hold for fittings, Dennis’ harness and a few other bits I moved to the bodywork.

I purchased a longhood extension panel from Michel Beaudry here on Pelican and began fitting it. Peeling back the front folded edge on the hood was difficult and required lots of hammer/dolly work to get it into a useable state, and that’s putting it generously. I fabricated a pair of pincers to help peel back the seam but even with them it was gross; lots of dents and dings. I understand the utility of doing this but geez, this was kind of ugly and in hindsight I would have probably been better off not peeling back the fold and just butt welding the extension panel; live and learn… This was also the first time that I got a bit uneasy about what I was doing; if the EFI/ITB fails I can always reinstall the CIS (barf) or have a shop correct my mistakes. With the hood it felt like a no turning back moment. Sure, I can always buy a long hood and replace this one but I’d rather save those sheckles.

Breathe. Breathe. Ok.

Once the panel was cut and tack welded I laid down 1,483,273 MIG spot welds. I wanted to TIG weld it but I’m not that proficient so it’ll be grinding, sanding and filing for penance. I suspect my reliance on MIG will be a theme that comes back to bite me later when my hands are numb from grinding and sanding them down.

http://forums.pelicanparts.com/uploa...1637012784.jpg

And with that the hood is long! Feels really great to have the panel on and seeing the car transform. I was very nervous about the bodywork (still am) but I feel much better now and am almost ready to tackle the light boxes and mirror holes. No doubt I’m going to be a stock holder in 3M given the amount of body filler I’m going to need but so what, a concourse car this is not and I’m not opposed to filler; lead or plastic.

A quick clean up of my studio and I called it a day.

A few questions for those who have been down this road before:

1.)On the fuel pressure gauge there’s a small hose barb on the right side but the X-Faktory manual makes no mention of what to do with it; leave it, cap it…?
2.)Charcoal canister- Right now the hose from the fuel tank is connected but that’s all. Do I need to connect the hose to the shroud and the other hose to the rain hats? Do I? Do I?
3.)Poll: I purchased both a small filter for the oil breather hose as well as a catch can. Real estate will be tight with the charcoal canister in place but methinks the catch can will keep the engine bay from being oiled up like a coed on spring break… Thoughts? (on the filter vs catch can, not the coed)

rwest 11-15-2021 01:06 PM

#2 yes connect to one of the rain hats.

#3, when I asked about an oil catch can and filter, I heard several comments that you still get a fine oily mist in the engine bay, so no coed and still a messy engine! I used PMOs and they came with a manifold to run all the oil hoses to and then to the rain hats- looks ugly and cluttered, but I was going for function first.

Nice work. I’ll add that you should look into BF Torino seats. They’ve got the look, are light and affordable.

ChrisHoover 11-15-2021 05:51 PM

My car had a small filter stuffed into a long hose. The hose sat on the engine tin. It was an oily mess. I put a catch can in. I bought a Moroso can. It it too big but the inlet is nearly the same size as the oil tank. Someday I may cut an inch off the height.

Consider crimped fuel line clamps.
In marine applications screw type hose clamps on fuel lines are frowned upon by marine surveyors.

Suggest a filtered breather type Catch Can mounted in the left wheel well with a drain valve, helps keep the engine bay clean.

RobFrost 11-15-2021 08:47 PM

Why do catch cans not simply drain back into the oil tank?

chrismorse 11-16-2021 06:28 AM

One breather approach
 
I think the breather, especiallly on a cold engine, may contain moisture condensate. With the stock plumbing set up, this is drawn into the intake and burned by the combustion process. If that condensate is collected with oil vapor, I"d rather not put that back into the oil.

Like Rutager, I did not want to risk oil vapors, via the stubby filter, or fuss with emptying a catch can.

PMO supplied a "T" fitting with the rain hats, (with Al's X Factory kit). I am running the big breather hose from the triangle of death to the oil tank, then the tank output hose to the T, where the two, supplied vent hoses go to the 90 degree fitting on each rain hat. The end of the T is threaded for a barb and i will use that connection to the T to receive the charcoal canister output line. I think i will tuck the canister into the back right corner of the engine compartment.

I too am concerned about fuel lines, so had Len, (BoxterGT), build a set of supply and return lines with stainless flex rather than rubber, (for the engine compartment). I used his tunnel lines and factory rubber, crimped hoses up to the new tank and fuel pump.

My ITB conversion has been stalled for rust repairs, duck tail painting, fuel line replacement, oil cooler and tank work by Pacific Oil Cooler, etc etc.......

Showdown 11-16-2021 06:33 AM

Interesting, so are you running the 25mm hose to the rain hats from the oil breather or down stepping it to something smaller? Also, won’t any oil vomit get stuck in those hoses at the low points or make a right mess of your air filters?

chrismorse 11-16-2021 02:42 PM

PMO breather layouy
 
Hi showdown,

If i am understanding PMO's intended layout, the big hose goes from the crankcase breather outlet on the top/back of the engine to the tank, then a big hose, (that used to go to the cis airbox, now goes to a plastic "T", then two smaller clear plastic lines go to the rain hats. the K&N filters are oil wetted to capture the dirt/dust before it enters the ITBs.
My sense is that the oil vapor that is being carried from the crankcase to the sump tank has a chance to slow down and likely leave most of the oil in the tank. the big hose then splits into two smaller ones and the remainder gets deposited on the air filter/through, to be burned.

the orriginal CIS air cleaner had a very small drain line that dumped excess out into the atmosphere, in front of the engine mounted cooler. maybe, on high mileage engines, (loose rings), the quantity might be noticeable. I haven't a lot of experience with this, hopefully, those with more blowby will opine.

:-)

Hi Show,

Looks like our cars are the same color on the inside- mine is still brown on the outside as well!

Here’s a picture of the device- the huge hose still goes to the crankcase breather on the engine, the breather hose by the oil cap goes to one port of the black plastic 4 port piece. The two top ports go to the rain hats, the last port is where the vapor canister hose attaches. This is basically how the CIS airbox was “fed”. The only difference is the airbox had a small drain hose if the oil quantity got to be too much.

I have thought about drilling a hole in the 4 port piece and connecting the old CIS drain hose, but haven’t yet.

I went with a simple filter on a 90 at the end of the vent hose tucked in the corner for now.
If it gets oily back there, I’ll go to a catch can before the filter.
A lot of my really old cars used to just have a breather before emissions regulations.
They weren’t extra oily. If they were, they needed repairs…

1. The hose barb is a manifold reference. It basically lowers fuel pressure when you let off the throttle, and increases fuel pressure (max is what you've set it to with the reference disconnected) when you mash the throttle.
Whether or not you choose to use it with ITBs is up to you...or your tuner. I've known folks to do both.

2. This IDK about. My fuel tank vent hose is plumbed to a rollover vent valve in the nearside front fender. (behind the headlight) I park my car inside my house and very seldom does it smell of fuel. This has more to do with temp fluctuation than fuel level. But like I mentioned prior, it's very seldom that my garage smells like fuel.

3. I really worried about this a lot when I did my ITBs. Everyone talks about how much oil/vapor moves between the engine and oil tank and I knew I intended to spin this mill as high as I could get away with. I spent several days trying to come up with some sort of clever catch can solution. I then consulted Erik Lind who said, 'just stab a filter on the vent barb on the tank and get on with your life'...or something to that effect.
So that's what I did. It's yet to drip a drop of oil in nearly 20k miles.
Emissions compliant? Hell no.
Messy? Also no.
Simple? Very.


Like you mentioned earlier in the thread, the journey (and tinkering) is half the fun. So if you opt for something simple and it fails, just revisit at that time. If you spend your whole life chasing some idealized/optimized setup, you may never get to really enjoy driving it.

Day 3

As a followup to last week's questions:

I decided to try the little air filter on the oil breather first and if it vomits all over the place I'll install a catch can.

I connected the charcoal filter but and going to omit the hoses to the rain hats for now. I can always add them later but I'm trying to eliminate all unnecessary hoses and wires; coming from CIS this is a compulsion, I guess.

----

My delivery drivers are visiting me on an almost hourly basis and the number of cardboard boxes is now a life size Tetris in the corner of my studio.

I woke at 4:30am and was at my studio before 5am with a head full of steam and a list of what I wanted to accomplish today.

By 11:30 I was done and headed home to tag in as a functioning parent and give my wife a break.

Sometimes you look at the day’s work and feel disappointed that more wasn’t accomplished. Today was filled with a mix of success and failure. Nothing that will stop my progress but the time required to address these issues (some that shouldn’t be issues at all) was frustrating and disappointing.


The Successes

I finally finished running the fuel lines with a switch to crimped clamps from the screw ones I had. I really like the location and tidiness of the fuel pressure regulator and vacuum manifold. I’m trying to be conscious of where every hose and wire runs in an attempt to keep it organized and looking clean.

I ran the ECU harness to the engine bay. I ditched the plastic cover for a flexible one as the plastic wouldn’t have made it through the tunnel. I’ll install a Deutsch connector where the harness enters the engine bay for easy engine drops, more on that later.

I drilled a hole into the SSI heat exchanger for the sensor bung. At this point one would expect the jitters of drilling/cutting/grinding nice pieces of kit to be gone but I still had to pause before punching a hole in my SSI heat exchangers. I bought a clamp on one that can also be welded if necessary. I’d rather not have to remove the exchangers so I’ll start with the clamp and pray that it cooperates.

I decided this week that I hated green and as such said goodbye to my engine shroud in favor of an amber fiberglass one. It required a bit of trimming and finessing but eventually it played nice. I really like the look of the amber shroud. The green was distracting and now the engine bay has a unified color palate, which feels and looks deliberate. This car isn't going to be a race car, nor is it going to be a juiced engine (yet) but I don't care and I like the fiberglass.

I made a mount for the MSD Streetfire; didn’t have any aluminum that size but I did have a piece if 1/8” carbon fiber. In addition I mounted a fuse panel and the lambda controller. I didn’t use the fuse panel that Al supplied as it would have taken up too much space and I wanted all the electronics to fit on the panel and under the plastic cover. Maybe I’ll make an amber fiberglass cover…

I pulled the tangles mess of the CIS harness and ran Dennis’ harness. Anyone want a Pertronix Digital HP? That was no fun and Dennis warned me that without an engine drop or lift it would be a bear. The harness is a thing of beauty but getting to the reverse switch without a lift is an exercise in frustration and cursing. I had to trim off a few inches from the Big Fat Red Wire as the one we measured against from Classic Retrofit was just too long, would have looked unkempt (and potentially interfered with the throttle linkage) and given it's gauge, bending it just wasn't an option.

FAILS

Because it’s basically Christmas now (it starts Memorial day, I guess) it feels appropriate to hoist my Festivus pole and share my grievances. Some of this is venting, and some is hopefully to aide in those that might come across these issues in the future.

Unfortunately the Deutsch connector I ordered weeks ago is stuck somewhere between there and here. I also had to get a 47-pin as opposed to the 23-pin I wanted because everything in the world is out of stock and delayed. That will have to wait until next week.

The X-Faktory supplied MAP vacuum hose is too short. I don’t know why it wasn’t longer. Huge pain to run the hose only to find out afterwards that it’s too short. Al's going to send me a new one; of course he is because he's a boss but I still have to wait for it...

SSIs don’t come with an O2 bung. Before they were sold to JP Group. They used to provide the option but no more and given the price for a set they should be embarrassed that one isn’t part of the kit. Price goes up and options disappear; hurrah! Seriously, if someone is listening, add the $10 to the cost and just weld in the damn bung, you can even call it an "upgrade" and make people feel good about getting a better version.

The Classic Retrofit Wosp alternator has a threaded shaft that’s larger than the Porsche original. The nut is also larger and has different threads; no problem there. The problem comes when trying to reassemble the pulley wheel and the little domed fitting that goes between the nut and the shims that clamps everything down. Because the shaft is larger, the domed fitting won’t fit over the shaft. I’m lucky that I have a mill and lathe and was able to enlarge that hole but given the cost of the alternator a new fitting should be included or at least a mention of this problem in the instructions.

The bolt that comes with the Rennline fan strap is too short. This has been a recurring theme with Rennline products that I’ve bought and I just can’t understand it.

Unfortunately the bumpers that I bought from Germany don’t fit so I’m in a holding pattern on them until the new Rennspeed bumpers arrive. I really think I ought to wait until I have bumpers before welding in the light boxes. Lord knows it’s not going to be plug and play. I'll be selling a whole bunch of bumpers soon so keep an eye out in the classifieds.

So a day with a lot of cursing, but no hurdle that won’t be overcome next weekend. Also, no skinned knuckles, so I go that going for me ;)

Happy Thanksgiving to all those that celebrate!!

J,
You bought two sets of longhood bumpers? If so, you're a wildman. I love it.

Keep going and keep pointing out the good with the bad. It may feel like useless griping some days, but it'll help someone else down the road.

Excited to see the new iteration of this car in the spring.
Hoping you get to go to Ruchlos 2 (II?) with us next year as well.

AlKidd 11-22-2021 06:03 AM

Keep at it. It will happen. I find all car projects, not just 911 take longer and cost more than planned. Have a question on your fuel lines. I tried to zoom in on the picture but it got a bit pixelated. It looks like your exiting the fuel filter at the bottom and then going to the FPR. Assuming return exits the bottom of the FPR and then mates to the hard line back to the tank? Is that what Im seeing?

LUFTKUL 11-22-2021 07:04 AM

I peeled the MSD StreetFire sticker off of mine. I like the inconspicuous black & silver box look much better than the look-at-me red sticker.

Feel the same about a few Rennline products I've purchased. I'm thankful they are a thriving business making unique Porsche parts, but I've had some head scratching on the fit and finish several times.

Showdown 11-22-2021 07:05 AM

Fuel from the pump to the top of the filter, out the bottom to the left of the fuel pressure regulator, out the right of the regulator and down to a T fitting, then off to the fuel rails. The return comes out the bottom of the regulator and heads left to the return line.

The return line is hidden by the manifold and the brake booster vacuum hose but it’s there.

The return line is hidden by the manifold and the brake booster vacuum hose but it’s there.

This is set up for double dead-head rails, right?

I have the same Aeromotive FPR, but I've routed my fuel lines quite differently.

My fuel lines run as such.
Tank -> pump -> filter -> 1-3 rail -> crossover hose -> 4-6 rail -> FPR side inlet -> FPR return outlet (bottom) -> return line -> tank

It's less hose, but then there is a crossover hose in plain sight. My thinking is less hose, less fittings, less chance for leaks/failures. And I can see the all the engine bay hoses and fittings without lifting the car. (not the filter tho)

Yup, double headed RHD rails. I’m running them this way because:

1.) it’s literally the diagram in Al’s instructions and he knows way more than I.

2.) less plumbing is less chance for failure

3.) (ain’t nobody dope as me) I dress (my engine bay) so fresh, so clean. So fresh and so clean, clean.

1. Fair play.
2. Agreed.
3. Don't you see I'm so sexy?

Thanks. Were you able to bend the inbound hard line to get it to the filter or just cut and join? Reason Im asking is Im setting up for a FI system and want to ditch everything but the filter.

There's no way that the fuel line will make that bend without a kink... maybe a braided one but not the rubber ones I have. Luckily Al's kit comes with a billion 90 degree bend fittings so I didn't have to force the hose.

The photos also show the mounting bracket I had to fabricate... All of $1 of aluminum angle and 10mins of work.

I was asking about the factory steel lines that look like they go into the bottom of your filter.

Oh, sorry, reading too fast.

I bought new cohline fittings from Belmetric to go into the bottom of the fuel filter. I reused the original fuel line that went into the accumulator- it just fit.

Thanks. Pic shows all I need. I havent pulled the CIS yet so working with limited space till I do. Just wanting to make sure I have all the lines and fittings before I start. One last thought though, I thought the fuel filter was directional?

It is, but I flipped mine. Normally the accumulator exits at the top and then goes into the fuel filter at the bottom via a long "S" fitting and then out the top to the fuel distributor. There are markings for "in" and "out" or an arrow on the filter just in case.

Turn it upside down and you don't need to mess with the fuel line from the fuel pump; it *just* fits.

Heads up however- I had to buy a few fittings from Belmetric to make the connection from the exit of the fuel filter to the pressure regulator- you might too depending on what your car comes with- there's a lot of variation.

Good news is that Belmetric has whatever you need. It's not cheap and expedited shipping isn't either but it's the donations we make to the P gods...

AlKidd 11-23-2021 01:11 PM

I think my filter doesnt have the step that yours does but to make it simple, I may just mount the filter where the accumulator is. Then it will fit.

Day 4

In every project a nemesis begins to coalesce and for me their presence has been laid bare: The Unites States Postal Service.

Body components and materials: delayed by the Post Office

Electrical connectors: lost in the bowels of the Post Office

Replacement electrical connectors: somewhere in the USPS ether with no indication that this box will fare better than the last two orders.

I would gladly pay twice the price if I knew for certain that the shipping would be handled by anyone other than the USPS.

Sigh.

With some careful negotiation, I had secured two full 8-hour days during this long holiday weekend to work on the car; it was supposed to be a mammoth session that saw the completion of the EFI/ITB conversion (maybe even a fire up) and major work on the body.

Instead, I worked a half day and all I could do was cut wires and start to run them…

So cut wires I did. After about 3 hours I was able to run all of the inner engine bay wiring up to the point where the delayed Deutsch connector will be. I was actually surprised at how easy it was, largely thanks to an incredibly detailed schematic by Dennis, the factory wiring schematic, and my harness being straight stock and unmolested. Once I get the engine running I'll sleeve all the wires and make it tidy.

With nothing left to wire I took the opportunity to daydream, look at Instagram, read every post in Pelican… and practice some TIG welding.

http://forums.pelicanparts.com/uploa...1638204149.jpg

This is not a gorgeous weld, it is not a stack of dimes and it will not win me a gold medal at Welding World 2022. But it is a successful >1/8” wide TIG weld using .023 MIG wire on 26 gauge sheet metal, which is basically tissue paper. It has me feeling confident that I might just be able to pull off TIG welding the light boxes to the fenders. The light boxes are such light gauge that I can’t actually imagine successfully welding them with MIG without major issues. When I bought them, I was assured that they were “very thick and strong” Sigh.

But of course, just as I was getting the hang of TIG on thin sheet metal… I ran out of Argon.

Ugh.

It’s incredibly frustrating to be hung up because of logistical issues that can’t be controlled for (yeah, I should check my gas regularly but the USPS really f*cked this stranger in the a*s)

I have to keep reminding myself that these delays are inevitable and better they are the result of shipping issues rather than car issues. Delayed package > finding rust.

Anyhow, hopefully I’ll be able to steal an hour here or there to make some headway before next weekend when I have to attend a wedding and will likely miss out on P Car time.

USPS has been nightmarishly slow since ~Nov2019.
And to add insult to injury, Chicago is the worst offender. There is nothing you can do except request alternate shipper or wait. I've been round and round with USPS in the last two years and there's just nothing to do about it. Even Priority and Express won't guarantee expedient delivery.

Best thing I can advise is to have plans B-F on deck for work days so you can keep moving forward.

Ain't that the truth.

I've started really looking closely at sellers and websites that allow me to use my own FedEx or UPS account as it gives me so much more control. Even if it's not the cheapest the shipping matters.

Wasn't it once said:

Fool me once, shame on me. Fool me twice, well you ain't gonna fool me twice.
