73 Dart back seat fit in a 70 Duster?

The 70 Duster I bought was missing its back seat (along with a few other things) :lol: but I bought a 73 Dart Swinger parts car a while back. Will the seat out of the 73 Dart Swinger fit in the Duster???

THANKS IN ADVANCE

P.S. I would go out and try it myself. But the cars are at my parents place 350 miles away.
