I am aware that 4th gen seats will fit nicely in 3rd gen, but how about the rear seat in the vert. Will the rear seat also fit out of a 4th gen? If so, does the seat need to be from a 4th vert or can it be from any body?

It appears as so the answer is yes. Doing a search found this topic. It provides some details as well as the last post did it in a vert.

Another good link . . .

It seems that the biggest concern isn't if it's a vert or not, but whether is the 3rd gen rear seat was originally split or not. If it's split, then there may be an issue dealing with a bar that runs across the driveshaft hump. But that's all covered in the above.

I've done the split to solid 4th gen rear seat conversion & the support for split seats wasn't a problem. I just left it there.

ah ha now i can quit looking for a seat cover to match. Them ther 4th gen parts cars. Ya gotta luv um......Thanks all...

The fourth gen rear seat back is about one inch shorter than the 3rd gens, not a big deal but there will be gap above the seat back that wasnt there before.

How do you pull out the rear split seats without removing the bar in the center? I am doing a 3rd gen to 4th gen seat swap and the new seats are solid.

To get the bar out of the middle, you'd have the chisel out the spot welds.

But I put the 4th gen solid rear seat in & never took those pivot bars out. I just left them under there. Doesn't hurt anything to leave them there.

In my GTA I have now, I left the split rears in there. Always nice to be able to only fold down 1 side & leave the other side still as a seat. I'd suggest leaving the split rears in & only swapping out the fronts. Might hafta reupholster the rears if your changing seat colors though.

what was done about the seat belt retainers for the back seat...?
did you take of the 3rd gens and stick them on the 4th gen back seats?
Appreciate the help... i did alot of searching and did not find a definite answer.
