So I'm fixing up my Firebird's interior. I found a 4th gen Firebird being parted and I know I can use the seats out of it, but can I use the carpet as well? Maybe with just some trimming?

 

Don't. I don't know if the 4th gen will fit, but even if it does, it is an absolute nightmare. While replacing my seats with 4th gen ones, I decided to get new carpet from stockinteriors.com. You wouldn't believe how hard it is it remove/reinstall all of the interior bits when replacing carpet.

The seats were so easy to install, it would have taken less than 1 hour. With the seats removed, you would be surprised how much dirt and crud you have under them. 30 minutes with a shop vac and resolve will do wonders for your old carpet when you have the seats removed. As it was, removing and reinstalling the carpet took about 20 hours.

 

my carpet only took about an hour

 

I am indifferent as to how long it takes. I just would like to know if its the same.

 

The dimensions of 4th gens are different than 3rd gens. So the carpet wouldnt line up. You could still put it in there, but I wouldnt recommend it.

 

I currently have 4th gen carpet in my 92. It "kinda" fits, but you have to trim and use a heat gun on the passenger front floorboard because the humps are different in shape. I only did it cause it was free and I didn't have any carpet to begin with. If I were to do it again, id buy 3rd gen carpet.
