Just picked up a '91 RS that has lexan t-tops, which of course are in rather poor condition. My plan was to swap them for the glass t-tops that were on my early build '91 T/A, but when I went to put them on, the side seals were about 2 inches too short in both the front and the rear.

Does anyone sell just the longer replacement side seals for the different style late 91-92 cars? Would really rather not replace every other t-top seal to make these glass tops work...

 

So I guess no one is reproducing these? Wouldn't be a problem if the seals on the car weren't so nice...seems a shame to have to replace everything just to change the t-tops.

 

You sure you have the correct ttop side seals? Aren't the C&C ttops seals shorter than GM seals?

 

Fairly certain...also I'm pretty sure all the C&C's were glass, mine are definitely lexan. My car shows the CC1 RPO code for factory t-tops, and the undersides of the t-tops have GM-looking labels on them. I can physically swap the glass tops on to my car, and they fit fine, the weatherstripping is just way too short on them.

 

I have swapped lexan with glass and vice/versa also and other than a mild design change they are the same length on all my cars. (I don't have any 82-4 cars)
Was just wondering if there were C&C seals in the one set of tops for some reason?

 

I suppose that's possible. The t-top weatherstripping is considerably nicer than the door mains and window sweeps.

I thought for sure that I read somewhere that the factory used a different style of t-top weatherstripping on late 91-92 cars though?

 

Its a minor change not a different style. They added drains/gutters.

 

Well I was kinda close...I knew they changed something.

At any rate, upon closer inspection, it's more like a half inch gap front and rear, which I can probably just chalk up to different brands/age of t-top weatherstripping. Nonetheless, it's enough of a gap to make the car leak like a sieve if it rains, so will have to figure something else out for them.
