    Will a 1955 Olds hardtop backseat fit a 1955 Chev hardtop. Ours came with a 2 door post backseat and they are completely different.

    The Pontiac will work. But the 2 door rear bottoms are different from the 4 door rear bottoms.

    I had a '56 Olds 88 front seat in a '57 Chevy once, and the bolt holes all lined up in the floor but the seat was a different design than the Chevy seat, so a set of Chevy upholstery would not fit. You might be able to make the Olds back seat fit one way or another, but they are not the same frame, so a set of pre-made upholstery is not going to fit.

    Pontiac shared most of the body shell with Chevy in '55 but the frames and floor pans are different, I tried a Pontiac front seat in a Chev and the width was good but the floor mounts were totally different (was shocking that the Olds seat fit, since they share no sheetmetal at all with the Chev), I don't really know about the back seat from a Pontiac hardtop though.

    Your '55 2 door sedan back seat frame is worth some money, I'd try to trade it to someone for a hardtop seat before I'd buy up some other GM seats and try to make them work.

    @Squablow (sort of) I dont think 2 door hardtop and 2 door sedan seats are different. I didnt know the Pontiacs had different floors. Would a Canadian Pontiac be an exact fit for a Chevy, while the American made ones might not work?

    Pontiac rear seat almost fits a Chevy...the floor is different, the hump is not as tall, so you have to trim the notch in the bottom of the seat. (I dont know about Canadian pontiacs, but I expect they would work, since they're Chevys for the most part)

    2 door hardtops have armrests like a convertible that are kinda built-into the interior panel, so the bottom cushion is narrower and the upper cushion is notched, they're quite a bit different than the 2 door sedan back seat, which is full width because the back seat arm rests are just little bolt-on pieces.

    This confirms what I was thinking. The width and package tray areas are the same, but with the different floorpan, I knew there was some difference in the Pontiac seat, and that makes perfect sense.

    Rear arm rests are determined by Bel-Air or 210/150, not hardtop or sedan. Although most hardtop were Bel Airs and sedans were usually not. I was told the seat bottoms were different for ease of entry on the two doors, and the four doors were a bit bigger because they were easier to get in and out of and were a bit squarer on the ends.

    Front armrests are determined by Belair/210 but I am unaware of any 210 2 door hardtops being built with a full width back seat. I did the upholstery on my dad's '57 210 2 door hardtop and the back seat in that car had the armrests that required the narrower seat, although I can't confirm that all of them were that way.

    The 4 door sedan/4 door hardtop has the rounded off back seat lower cushion for entry and exit, the 2 door sedan has a full width, squared off seat lower cushion. 2 door sedan and 4 door sedan use the same back seat upper cushion, not sure if that is true of 4 door hardtop/2 door hardtop or not.

    I think the 4 doors all share the same back seat.

    Sedan and hardtop seats are completely different regardless of what trim level the car was.
