I've got a 91 firebird with factory t-tops, and I got the seals ripped out and the aftermarket ones I had looked different and did not fit in the front. I also was told there is no way to get a hold of any gm seals, so I was suggested to buy either steel rubber or soff seal brand t tops. Which brand is better? Any other recommendations or suggestions? Thanks for any responses.

While I don’t have t tops I used soff seals door weatherstripping and was a bit disappointed to say the least. The factory weatherstripping had a sort of plastic support at the top corners of the doors. The soff seal does not and while it works just fine I know other company’s include this plastic making me regret buying the soff seal. Again this is just my experience with soff seal door weatherstripping so it may be better quality with your t tops.

My wife's t-top has soff seal and they fit great.

Mine has OER (total junk)
