I have an 87 firebird I'm gonna sell ,was gonna swap the t-tops with my 83 TA ,cause the 87 has locks on them . but the 83 has a plastic trim peice all around the out side and the 87 does not ,since I'm gonna put new weather stipping on the 83 does it really matter if the plastice piece is missing, or will it be too loose in the center track .

 

iIam not sure, i dont think it would matter i think that the t-top's were made about the same, i think all that changed with them where the way they locked, the weatherstripping, and material their made of. If they fit, they must work! When swapping test for any leaks also another way to tell if they worked.

 

Do you guys know if they made different size t-tops for pre 88 fbodys. I have a 91TA, my buddy has a 92, other buddy has a 88 and my dad has a 90, they are all the same. My other buddy has a 87 and he shattered one top all over the interior. We can't find a replacement cause nothin fits. His ttops are a good 2 inches shorter, front to back, than mine. Any ideas if his may have been aftermarket, or if they are dofferent from the factory. Any ideas where to get these things? Junkyards aint workin out. Thanks!
