Nope.....Not at all. That is why hundreds of us already have them bolted in......

Re: will 4th gen seats fit in 3rd gen?
No, they don't fit.



Actually the electric seats sit higher and they feel kind of weird even though I'm short. It's probably a good idea to find some manual tracks if they're electric. Mine are from a '95 I believe. I also gave away a set of manual tracks to someone else in a similar situation except they needed them more than I did.

BTW, I'm assuming every time you did this you were using manual brackets, and not electric seats.

Re: will 4th gen seats fit in 3rd gen?
I've never seen the point in electric seats. I sir down the FIRST time I get the car.....
Slide it back 100%.....
Done!
Even when I've had cars that came with electric seats, they only got moved ONCE.

Re: will 4th gen seats fit in 3rd gen?
I've got Electric 4th gen seats in my 84 Firebird from a 2000 T/A. Used the 4th gen brackets. The bolt holes lined up 100%. Only thing I had to do was fix the wiring to work with the drivers side seat. Like Stephen said though, I've moved it exactly once...when i first sat in it. The 4th gen seats do sit lower in the car than the third gen ones and are SOOOOO much more comfortable. If you do a search on the boards you'll find probably 1000 threads and posts about people who have already done this conversion.

In the weight reduction thread, they say 4th gen seats with 3rd gen sliders is a noticeably lighter combo.....

Re: will 4th gen seats fit in 3rd gen?
But if you have & want to keep the split rear seat back cushions, 4th gens never came with those. So you might not want to replace the rear seats. I didn't. because I kept my split rears.
Re: will 4th gen seats fit in 3rd gen?
Direct fit. Bottom cushions about 1"-2" narrower. So if really look at the sides, you'll notice the tiny gaps between the cushions & tunnel/plastic panels. Difference isn't worth worrying about.

Re: will 4th gen seats fit in 3rd gen?
On 3rd & 4th gens, the bottom cushions are 2 individual ones.
The BACK part, what your back leans against, is what I was referring to. Some 3rd gens had a single wide, fold down back, some had a 2-piece, fold down cushion. Mine has the 2-piece, so I just left the rear seats alone.

Guess it's time to start searching "most popular mods" and "common problems".
