Okay, my body guy has painted the car and is ordering parts to install the windshield. If I have the 15 mm pinch weld flange instead of the 10 mm flange, I'm going to go for it with the 964 windshield.

The car is a couple of hours away. Can anyone explain what reference point the 10mm and 15 mm measurements refer to? Is that the top/outside or inside of the flange. Measured from the bottom of a curve or the top? I could use some help on exactly how to make the measurement.

Thanks for all of the help.

The flange is perpendicular to the window opening, The measurement is the width of the flange, from the body to the outside of the flange itself. You should just determine which flange you have by the serial number of the car.

For what it's worth, if your not a purist I gave up on the putting a 964 windshield in my 1977 car. I actually installed a 993 glue in windshield and it fits great.

My car lives out side in Florida nd I didn't want any leaks. For sure the 993 conversion will never leak, is flush with the body for better aero and stiffens the car up.

Wow, super. I'm an engineering purist, not a originality purist. Better aero and the added stiffness of the glass is great. I had no idea that a 993 would fit or work. So, I need a 993 windshield, glued in, and a 993 seal, correct?

I'm wondering about the 993 also....

2 seals, inner and outer. You can do the 993 rear also, as well as the quarter window seals from the 993 which will flush out your quarters.

Couple all this with shaving the rain gutter and you'll have a fairly slick 911, aside from the door glass recess. Of course, you should do the RUF/935 aero mirrors then, also...

Pelican only lists one seal for the 964 and 993. How does this work differently so it fits? The windshield glues in place, and then the seal wedges in around it? Is it a different sized glass that just fits?

Sorry for all the questions, but this sounds like a great solution.

Phil?

993 front and rear--How is the glass and install for the rear different? Do I need new glass. Does the 993 glass have heating elements like mine?

Two seals for the front, huh? I wonder why I can't find them provided by our host.

The quarter glass won't work, I've backdated to opening front and rear quarter windows (something old, something new).

There are two front seals. The inner one goes in place over the flange first. You then take presicely the correct amount of urethane windshield glue and extrude it in the space next to the firts seal. This will become clear when your standing there with the windshield. The reason for the correct amount of goop will become evident if you put to much because you will see it on the inside of your car after the windshield has been pressed into place. The next step is to place the glass. It must be centered correctly to get the outer trim to be correct. Once it has dried the outer trim clips into a groove in the windshield plastic surround that comes with the windshiels.

That said, I did this install myself but you need to research this untill your comfortable doing it. The glue is very tuff stuff. It's a one time only process that required a knife and steel balls to undo.

I like the 993 idea. Ryce, do you have any pics?

Tried to do it the right way. Bought what is suppossed to be a 964 windshield for my 92 Turbo coupe. Put on the 994 seal and dang the windshield is way too small. Go figure!

The windsheild looks like this.

I just installed a 964 rear window and seal. I can tell you for sure the SC rear window is about a 1/2" smaller top to bottom than the 964 and the 964 seal will not work with the SC glass.http://forums.pelicanparts.com/uploa...1183572300.jpg http://forums.pelicanparts.com/uploa...1183572397.jpg

I have a question. Who says a 993 rear quarter window will not fit an SC? Others ahve posted that it will. Who knows what?

Another try
 

Wow....that really looks great....something I will have to seriously consider for my '88 once I start working again....awesomwe thread, thanks everyone...so far!

Dammit, my 993 window is too small.
 

My body guy just called to tell me the 993 window guys showed up and tried to install the glass, and there wasn't enough flange to glue it in. Ryce, did you use 993 glass, or just a 993 seal and glue with earlier style glass? Your fit looks great. What year is your car?

993 glass in a 1977 911.

Post a picture of the inside of the windsheild. The reason I asked this is that I intalled a used 993 windshield and shaved away what I thought was the old urethane glue from the inside. This is the only thing that might be different from your installation. Gilbert at Vertex in Miami has done this install several time and it seems to work fine. Did your installer put the inside seal on the flange first? This seal moves the windsheild away from the body a little and helps the fit.

so will a 964 screen and seal fit a 76 911

Actually, after talking to him again, it sounds like the install will work fine. He is just unfamiliar with newer style windshields, and the glass guy he is working with has not done a newer Porsche (middle of central Illinois).

As he describes it, the seal covers the entire flange, but there is a taper on the seal towards the outer edge that makes a V space. So, in effect, the windshield will be glued to the sides of the windshield opening, not directly to the flange, and the glue will contact both the underside and the sides of the windshield. Does this sound correct?

Subscribed.

that is correct! Trim headliner away from sides of windshield opening, if necessary to bond the windshield to the body directly.

Your installer figured it out. The trick is to use the correct amount of adhesive. To much and it will ooze past the inner seal and to much on the outside will make it difficult to get the outer seal flat.

I like this mod for my car because here in the tropics where it rains alot all Porsches leak except ones with glue in windshields.

Well, my body guy seems to think the windshield sits too proud relative to the body with the 993 seal, so he called in a windshield guy. A bunch of windshield guys wouldn't touch the job, and the guy who came out to look at it gave me a whole song and dance about how bad the design is, and how he can't accept the liability of doing a non-standard install. Not having seen the setup, my engineering judgement tells me he is full of it. That said, I have a few questions:

Is this install identical to the 993 install, or does the 993 use of these seals produce a different windshield/glue/body geometry. The glue just connects the outside edge of the windshield to the body, with a little fillet below?

Does the 993 innner windshield seal need to be compressed to install the windshield? My body guy seems to think that installing the inner would leave the outer too far out, and not touching the body. What is the technique for compressing the inner until the glue seals.

Does the outer rubber glue to the inner rubber when the windshield is installed, or is there another system?

Is there any other technique to getting things centered and compressed so I can just get the car back with the old windshield reinstalled, and then fix it myself?

Phil

Bump. I need a hand here to finish this up. Anyone installed a windshield on a 95 to 98? Did the seal need to be compressed?

I got one installed but I haven't seen the car yet so I can't say how the fit is I can ask the shop on Monday about it and get you some answers.

Was it installed in a 993 car, or was it an upgrade to an earlier car? The big question is if the rubber needed to be compressed.

Bump.

philipguziec, the 993 winshield with the 2 correct 993 seals should work just fine in your car. Check Matteo's thread for pictures - we used 993 front and rear winshields and correct seals, and 993 quarter window seals with the 1974 quarter glass on that build.

Additionally, we used a 964 front windshield and 964 seal in a a 930 build recently - that thread is in the 930 forums here on Pelican.

Jack

Do you get that cheap windshield glass because you are a frequent repeat buyer? If so that means you're spending way too much time on the track and good that you're lapping all the backmarkers....

wj

Phil the seal and glass are 993 pieces in my 930

The inner seal just fits over the flange. Once it is in place you put the adhesive on the body to the outside of the inner seal. It should be obvious where the adhesive goes at that point. You just place the windshield in and seat it to the adhesive. That stuff is very sticky and the only thing you need to do is place settling blocks at the bottom of the windshiel to keep it from sagging down untill the glue is dry. You then snap the second seal into the groove in the 993 windsheild. You can do this without adhesive as a dry run to check the fit for the second seal. It should be flush with the body. Refer back to the picture I posted that shows the fit.

Thanks for all the help guys. This is the last thing. He's talking about gluing in the outer seal, and it not sitting flush, so I think we didn't have a 993 windshield. I'll see if I can get him to do it.

The windshield itself has a groove in it, correct?

Sounds like my body guy and I will be doing the windshield ourselves. He got it to fit.

Anyone know the exact type of glue, part number, tube size, and where to get it?

Phil

Woohoo, it's done. The 993 windshield fits and looks great on an 89 930.

Next PITA problem. The rear view mirror clips on differently on the new windshield.

The windshield has a square-ish male fitting. I ordered a mirror from our host for a 98, and it has a male tongue and clearly doesn't fit. Pelican actually lists the same part number all the way from the 78 to 1998.

Any idea where I can get a mirror that fits my shiny new 1998 windshield?

With 993 rubber weather strip? Does it look great? Does it go in straight forward or you need any trick? Can you tell a little more deatail, or can you write an instruction?
Thanks phil.

Yep, the 993 with the rubber strip drops right into the 89 window frame. The instructions are excruciatingly clear in this thread.

I think it looks great, and it quiets down the wind noise quite a bit. Of course, I shaved the rain gutter at the same time, so I'm not sure which change reduced the wind noise. I bet both.

I also filled the antenna hole in the fender. The in-glass antenna works okay, but I do have some AM reception problems, and problems in high density city areas with the FM.

pictures...!

This is really good stuff guys.

I like the idea of going for a 993 window, both to avoid damaging a 964 window while pulling it in place as well as to make sure I have no leaks.
My 964 window is out now due to a crack and the need to redo the lower corners of the window frame (rust).

@ Phil and Racey:
Before installing the outer seal, what did you do with the space between body and the glass (the area that is normally filled by the traditional rubber seal) ?
Is there a way to make sure that no water gets to sit in the lower corners anymore ? For example by entirely filling it with sealant before attacheing the outer seal to the window ?

When you glue in the 993 windshield, I don't think any water will get past it to rust that area. Bacially, you're filling the area with the glue because the 993 windshield pushes the glue out to fill the whole gap.

In my case, we put a little too much glue in and some of it got over the groove that accepts the outer seal, so we put the outer seal on before the glue dried to make sure we could get it in.

Thanks for the clarification; I could not get an idea of the size of that gap under the outer seal. If if fills up the entire area, that sounds good.

Have you checked the difference in size between the 964 and 993 windows ?
Are they very different ?

@Phil: what did you mean with "I shaved the rain gutter" .. ?

You can always go around the window and add glue if necessary to completely fill the gap.

I didn't pay attention to the size difference, but the 993 fits the outer opening, which is constant, I believe, from the early cars through the 993.

I had my body guy cut the rain gutter off, a foot at a time, and weld the three pieces of metal that meet in that seam together. The result is a smooth look, less wind noise, less drag, and better downforce on the tail. You need to take the interior out, and repaint the car. You can search for shaved gutters to find threads about it.

Some people find this offensive for some reason, and are paranoid about rain water runoff. I, however, have not had any such experience. My body guy now wishes he had shaved the gutters on his car.
