Rear seat compatibility

I have a 1970 Duster and it doesn’t have a rear seat. Are there any other Mopars of any other years that have a rear seat that will fit right in my car? I don’t care about the patterns in the fabric or the shape of the foam. I just want the frames to fit right.

Thanks

If I remember right, there is a how to thread to convert to a later model duster/dart sport fold down rear seat back for the early dusters. You may prefer that. I think @72bluNblu did that conversion on his duster.
