72 duster rear seat covers vs 70 duster rear seat

Hi y’all,
I’ve got a 1970 duster rear seat and I’ve got a buddy that has new seat cover upholstery for a 1972 duster that he’s not going to use. He said he would sell it to me. It the standard vinyl upholstery cover with no inlay in it and it’s for a fixed seat and the 70 rear seat I have is also a fixed seat. My question is, will a 1972 duster seat cover fit a 70 duster? Thanks for any help in advance.
