are these seats correct?

Can anyone on here verify that these seats are correct for a '71 duster? They'e in really good shape, but I haven't seen buckets with this upholstery pattern before. Then again, I'm relatively new to all this. I'm guessing it's probably a lower grade interior because this car was originally a slant 6 (?). Any help is greatly appreciated, and sorry for the low quality pics.
