Dan is right. You would have to be nuts to buy some of the other seats that are made for a chevelle - glide engineering... when you can buy awesome power seats at a wrecking yard for a few bucks. I put 6 way power seat in my 64. I think it was out of a 90's Pontiac full size. I had them re-upholstered by a guy and cut down the head rest to look like a 70's chevelle (or you could remove the headrests. The front of the mount bolted right up, I had to cut and weld the rear part...no big deal and it is just as strong as stock....if not stronger.
