'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!!
