69-72 and 73-77 rear bench seat difference

[hunter_507]

So I bought a 70 Jimmy that didn’t have a rear seat, found one on Craigslist and the guy claims it came from a 72, but it definitely looks like a 73-77 as it’s red cloth, and has normal looking brackets on the front (not the bars that use the floor clamps). He only wants 100 bucks for it. I know the brackets aren’t the same, but is the frame itself the same, and if so is the foam close enough that it could be shaved and reshaped to take a 69-70 cover? I’ve been looking for a while and all I see are benches for 1k+ that still need recovered. I figure if this takes me a couple days worth of work it’s worth saving the money.
