A Body Bench Seat Swap Question

Does anyone know if the Bench seat from a 72 A Body Dart car was a match/mate for the 71 model year Duster?. I'm thinking of swaping my buckets for a Bench Seat with fold down Armrest, but before I do, need to verify if the seat will bolt up okay or if I'll encounter any installation issues or appearence issues with the 72 model year seat.

Can anyone shed some light on this for me? My build sheeet shows the Duster came with a bench seat C-52 code, but I'm unsure if it had the fold down armrest or not. Anyone know? Thanks Guys...
