'71 Duster bucket seats......Will 72 covers work?

I have a nice pair of bucket seats from a 71 Duster. Will seat covers for a 72 Demon fit? They seem different, Im not sure if the padding is that much different??
If not, does anyone make the foam for 72 Demon buckets?
Are the frames the same?

What about the rear seat? are they all the same frame/foam??

Thanks!!

the 72 seat covers will fit for sure. the only thing I'm not sure about is the "pillow head rest" on the 72 seat cover. Is it in the seat cover already or is it part of the foam for the seat? Rear seats will fit....
