Are rear seats interchangable on all A-bodies?

I have a 71 duster. I need the rear seat ( just the back part where your back rests on) I have the bottom part. Will any A body rear seat work or do I need specific year and model?

Thanks,
Wizard

You need a seat from a Duster/Demon/Dart Sport, non-fold down if you want it to fit right.

A-body rear seats are different heights depending on the model, 2 door hardtop seats are a different height than the sport body seats, 4 door seats are a different height than 2-door hardtop seats. Barracuda seats are different fast back to notch. One of the barracuda seats interchanges with another model but I forget which.

There's a guy here locally who is advertising his a body fold-down seat as a fold down conversion.. lol...
My Hope Is some unsuspecting enthusiastic new to the Mopar scene person doesn't believe this and over pay for something that won't fit in his car without one hell of a lot of other parts and attachments let alone the back deck and everything else....

It’s really not that hard, and you don’t have to replace the entire package tray
