79 SC Targa window seals

[Robey5]

I put another hour into it, and got the glass aligned as much as this guy is going to be aligned.




So: from here - I tightened all of the various Allen-head bolts to lock this glass into place.

Then, I lubed the pall-gear.



Along with all the remaining moving parts in the door shell.


Then, I put some final touches into some of the things that were missing when I started this project: which are often overlooked on these cars.




I know that plastic plugs and such should not really excite me as much as it does, but hell - it looks so much better.

This next segment id like to call “the finishing touches” to this job, because ... in many respects, this car has had a lot of neglected bits and ‘finishing touches” in it’s life.

SO:

I started to clean up the door panel and prep it for the door card.





I started to think about my goals in “finishing” this project, when I saw this problem....




This cracked area is kind of common in these cars, and many people have addressed this in a number of different ways. The driver side is perfect, but this (the passenger side) looks like dookie. SO: this is the way that I made the repair:

I used one of my little part-cases-drivers and used a generous amount of JB, clamped it up and left it to sit over night.







I figure that if I have to open the hole up any after the job is ‘done’ I can hit the little green thing with my drill. So that I can disguise this repair, I will also hit it with some vinyl (black) that I have laying around from a previous job.

Then, ...... big league thank you to the host here: I received my replacement outer squeegee for the driver side, and man, that looks so much more nice.






(Look dad, no gaps!)

[Robey5]

OK:

today, I buttoned it up to a point that I am going to have to wait for some butyl caulk and black tape to finish this job.






As you can see, I disguised the repair I did on the pocket pretty well. I do not think that the average joe will notice the repair.

Next, I will install the driver’s side lower door seal. Also, I reached out to Dan P to get my hands on a proper front targa seal.

Great thread with great work

Today; I received the butyl caulk in the mail, and I used a total of about 16 inches of the 50 feet (!!) by re-creating this gasket:




I then decided that I needed to test my work. ... I took it on a corona-cruise. It was not a very long drive, just to the highway and back so that I could get her up to speed to see if I addressed all the wind noise. IT is MUCH better. As in: I can hear myself think now. However, we have a little more dialing-in to do on the top itself.



There is about a 1mm gap that is above the vent window on the driver’s side, and the glass system is as high as it will go.

It’s tough to capture in a picture, but its there.

SO: I watched the YouTube vid again (in German) and watched the guy fix the targa seals, and one of the areas he addresses is the side seal on the top, he puts a shim in there (additional rubber, I can only assume) and the seal is then watertight.

Now the decision is: do we go in for these (glass top) seals now as well? Or attempt to work with what’s there?

[Robey5]

Holy smokes. I just took a look at the cost of the “lateral seal” and I have a good amount of heartburn. That and .... the URO option did not review well. I will be poppin the top and seeing if I can work with what I’ve got.


Sheeeeeeeesh; I mean ... I suppose that I would have dug in to the pocket if the URO option did better in the review department..... but that “P original” come on, guys.

[Robey5]

Today, I decided to pop the top off and see if there were a couple adjustments I could make on the “lateral seal” of this thing to eliminate the remaining gaps.

I figured a system of tape and post-it notes would be good to mark the gaps.





Armed with my seal-stuff, and tools: I got to work on the dining room table.





I was able to get the pass-side *perfect*

... but I had to go at the driver’s side a couple times to get it right.






I got the lateral seal to touch the glass, and in review of the existing “lateral seals” I can say that they are not in the greatest of shape. Perhaps (maybe) they’re due for replacement like the other seals, but the P-car guys aught to be ashamed of themselves. $250 a side? If (and ONLY if) I could get a fair amount of reassurance that my lateral seal-to-glass would be solid - I would consider this purchase.

@Robey5, fantastic thread. I bought some new speakers for my '76 Targa which as lead to me wanting to replace every seal in the door due to some water damage and general desire to refresh things. My biggest concern is that my window alignment is pretty good. I have manual windows and they contact 99% of the bar and lateral seals.

My question is can the vent window frame be removed without removing the main window glass and regulator? I understand the long track the window rides in would come out, but I don't think that would be a major issue.

Also I compiled a list of door mounted seals below. The only one I'm missing is the vertical felt piece that is in the window guide. Not sure if someone has that, but would appreciate it!

Edit: I think it's 911-542-905-00. However the pictures appear to be for 3 sides (coupes). Can you just order one for a Targa and use it for both sides?

911-542-066-41 (Top Right Window Stop)
911-542-065-41 (Top Left Window Stop)
900-056-003-20 (x4 Rivets for Window Stop)
911-531-951-01 (L/R Interior Window Felt)
911-531-932-42 (Right Outer Rubber Seal)
911-531-931-42 (Left Outer Rubber Seal)
901-531-936-20 (Right Inner Felt Seal)
901-531-935-20 (Left Inner Felt Seal)
911-542-136-40 (Right Moveable Vent Seal)
911-542-135-40 (Left Moveable Vent Seal)
901-531-933-20 (Upper edge vent glass seal)

“fantastic thread”

...holy cow! I just got some street-cred. ...maybe.

So: regarding the way that the vent window comes out I *believe* will allow you to do so without pulling the rest of the reg, however (in my experience) I would not bother because the room that is involved with all those parts is minimal, and if you are equipped with hands of normal size, you are going to beat your hands up pretty good. Plus, with that front felt strip, it is much (MUCH) easier to replace that felt channel with the whole reg out.

Further 911-452–902-00 is not found when I google, but I can dig a little deeper to see what I picked up to replace those parts. I DO know that this seal was from a coupe, and I purchased 2.

Now; a point for a tip:

Do the passenger side first. You will have lessons learned from the passenger side that you can apply to the driver’s side, and there were more wires on the drivers side (for me, at least).

I did a little more searching and it looks like the metal bracket that holds the glass can be removed from the regulator without adjusting the alignment settings of the regulator. The slotted holes have a large opening on one side that the bracket can be maneuvered through and the glass assembly comes out pretty easy. I'm anxious about messing with any of this because it is aligned and working just fine as is... The "while I'm in there" bug is too strong to ignore the seals, though, before I put new door panels and vapor barrier on.

I'm going to try this method first. Since I have manual windows, only have two wires coming into the passenger door. It's actually pretty spacious, but I can see how the outer felt strip needs the window removed.

[Robey5]

Jon:

I think that I found the part that you are looking for. I *think* that you are looking for the “GUIDE” (felt/rubber that is inside the metal track that is holding the glass in place while in motion) - that part number is 911 542 505 40.

Also, it appears that this part number is one that is made specifically for the targa, which makes some sense seeing that I believe that the coupe version has corners and all.

Discrepancy between old and new window seals (911-531-951-01), upper inner window seal at top of door, ‘86 911 Targa.

I purchased replacement window seals using the PET Katalog part numbers. However, the part I removed from my car is different than the new part. Both seals attach by pressing them down onto the upper edge of the inner door sheet metal, just behind the leather trim piece at the top of the door card. The old part has felt on one side, and nothing on the other. The new part has felt on one side, and a squeegee on the other. The new part is the correct part number (911-531-951-01), and is identified as such on several Porsche part supplier’s sites, but the new part does not appear to fit correctly.

Pic#1 – Part comparison - the upper seal is the old part removed from vehicle and bottom seal is the new part.

Pic#2 - new part partially installed, which does not look right to me.

Experienced guidance is requested.

[Robey5]

It looks like the new one was slightly re-designed so that the leather to rubber gap could be concealed a bit more nicely. However, when looking at my crap-mobile, my replacement glass felt does not have the fin-feature that your “new” part does. Frankly speaking: I’d trade you if you’d like.... Maybe you can (assuming you purchased from the host) reach out to the tech-support to ask if there has been an error or supersede action taken on the part.

[Privateer383]

I made a couple calls to Porsche dealer's Parts depts in my region to inquire about the difference in the old and new door felt/seal (911-531-951-01). One dealer could not verify either way. The second verified that the added "squeegee" is the new design and the only design currently available. Thank you"Robey5" for your trade offer, but I'll have a go at it with the "new and improved" design.
