    What I was saying was that the seat back cushions for the Olds/Buicks were different then the Pontiac/Chevy. The 70 Olds and 70 Buick front seat back cushions are not the same.

    A very common complaint when replacing entire seat springs with reproduciotn ones (made for Chevelles and every one sells them to us because we all know all A bodies re the same).

    The hot tip is to repair broken springs with proper gauge spring repair material

    I don't mind it. I know it'll settle over time.

    It's like a brand new car. :D:D

    Yes the 70 Olds seat pattern does not have the Upside down U pattern like a Buick.

    When I had the upholstery business going I always hated reproduction seat cushions.

    I would go out of my way to repair the original cushions instead of using repros. After a while I got very good at repairing original foams.

    Once I did a pair of 65 Corvette seats with new cushions, and the only way we got them on was to hog ring the centers in, get someone to sit on the seats, pull the covers on the rest of the way, hog ring them in, and then have the guy get off the seat. (and this was after we cut 2" off the bottom of the cushions.)

    The covers looked great, but when the owner came in to get them I told him if he ever Farted and the seats let loose, he was probably going to nail the windshield.

    Another thing to remember is this, the foam expands at something like 30-1, so if you inject a golf ball size amount of extra material into the mold you end up with an extra volume the size of at least a large grapefruit. This means the density of the foam gets that much greater. I remember one upholstery guy that ran new cushions thru an old ringer washer machine to "break the cushion down some" before he would use them.

    Thanks for the clarification. My guy already told me I had to wield the hot knife! :confused:

    Duane sounds like a great idea for an ejection seat on the passenger side for bad dates.
