will a back seat from a 72 work in a 75 duster?

You did not mention if your car has the fold down back seat, so I'll assume not. It uses a different back.
Other than that, 70-76 Duster,71-72 Demon and 73-76 Dart Sport. The Swinger/Valiant style is different and the 4 door darts are different.
I'll be bringing several to Carlisle.
Good Luck!
