Can anyone tell me what to look for to tell the difference between a 55, 56 & 57 front seat for 2 doors? I've seen some ads saying it's a 55/56 but it'll work in a 57 with slight re-working. I actually would prefer a 57 2 door front seat. Pic would help with the differences noted!

Thanks,

Dave

The 55,56 seat backs are about 5" thick with an overhang/ledge on the back side/top.
The 57 seat back is thinner, about 4" thick and the top comes to more of a tapered point at the top middle.

Thanks for the info guys! I currently have a 65 split seat in the car, but it's a little too wide and contacts the door panels. Just wanted to know what to look for in case I see something out there!

Thanks again!!

I went to look at a seat yesterday from a 55 or 56. The owner wants $650, but is open to offers. I'm thinking that I'll keep looking for a 57.

You can do better than that for $650..Of course since you are in Canada,,???

I saw 2 seats at the swap meet today. The first was a 55/56 2dr seat, price...750.00. The second was a 57 2dr seat, price....900.00. Good deals on them are few and far between from my experience.

I'm finding that it's not as easy as it seems, at least here in Canada. I looked at a 55/56 last week, he was asking 650, but said he was open to offers. I do have a line on a 57 front and rear seat that the guy is asking 900 for, but I'm having a hard time getting some pictures from him, he says they're in storage. I'm slowing working with him, plus I have some ads out there. I'm thinking I could always find something from a late model to use for now and if, when, I find a seat, then I could re-cover it and install it.

Two more questions:

Are the actual metal frames on a 55, 56, 57 the same and just the foam contours different making the 55-56 have the bump out on the back that's not there on the 57? Meaning, if you found one in rough shape, could you purchase new foam and covering to make a 55-56 into a 57?

Are Pontiac seats the same as the Chevy? Again, if you found one in rough shape, could you purchase new foam and covering to make a Pontiac into a 57 Chevy?

Thanks,

Dave

I have a 55 Pontiac seat that I might put in my car. It bolts to the floor in the same location as the Chevybut might sit a little taller than the Chevy due to the way the seat rails are attached to the seat frame. The shells are different. I am sure some modification would be required to install Chevy seat shells. Would be nice to have a Pontiac and Chevy seat sitting side by side.

I took a few pictures of the US Pontiac seat and attempted to hold a tape measure for reference. If somone could measure the seat height of a Chevy seat we would know the difference. Maybe swapping the seat rails would bring it back down to the Chevy height.
