Fastback weather strip issues..help!

[bill340S]

Sure wish I had researched here before paying to have my new windshield and cherry fastback rear glass installed. My 69 Formula S is being restored at a shop and I have been supplying the parts I've purchased over the years as needed. I used old (new in the bag) PC (Taiwan) gaskets (my bad) and the installer said he "made it fit"! Then I went to the shop to see the car and OMG! What a total mess. I need top quality gaskets. This thread has people bouncing back and forth between Steele and Precision Rubber. At this point I don't care what they cost...just has to be perfect fit. Don't want to do this job 3 times. So what should I buy. Steele advertises their gaskets have "correct corners". I haven't been able to find any pictures of Precision parts. I can tell you the roof corners on my rear glass with these junk PC gaskets have huge pockets between the trim and glass that I can stick my small finger in the gap. If you have done a fastback and are happy tell me what you used, please.

We have sold hundreds of Precision gaskets and slightly less of the Steele gaskets. Depending upon the car model and year, one may fit slightly better than the other. For your car, we have not had anyone complain about issues with the Precision gaskets. Precision is an OEM vendor, so it is not like they are making junk. Steele has a bit better coverage for some of the more odd applications and earlier vehicles.

Thanks for the feedback.

It's possible Precision has made mold improvements since I bought my gaskets over ten years ago, who knows, but the old gaskets fit poorly and had the same part number as their current gaskets. WCRD690 windshield WCRDB3847 back glass. You can't tell how good they will fit until you actually begin installing them.

Does it go in the same way as a 67 Charger?
I.e. gasket first and then glass into rubber.
Then a zipper type arrangement to lock the rubber.
With a lip inside at the bottom to cover the dash frame screws.
If so what a nightmare.
I fell sorry for your glass person.
I just did one. The lip does not lay flat inside
I tried two.

And don't even ask about the back glass.
Chrysler did not ever plan for that to come out.
No provision in the trim clips to get a tool under them.
Rubber was a terrible fit.
From one of the manufactures mentioned here.
Maybe the factory had better fitting gaskets to begin with????

Yes, my installer used tape to hold the gaskets in place against the body then work the glass in the grove with pull rope. The rear gasket was a real hassle. When done the tape just gets trimmed with a razor blade. And yes, the rubber does not lay perfectly flat on the dash.

Did he use separate rope sections instead of one piece of rope like when the gasket goes on the glass first? I've done the rope thing when the rubber is on the glass.
The reason I asked is because I'm familiar with that. The rear glass can be put in like that and some windshields.
But since the rope has to go into an inside groove of this type, mine kept coming out at the corners when you pulled it.
I'm thinking that if 4 separate piece were used, one for each side, then the corners could be worked in as needed with a shoe horning method .
