interchangeable Duster doors?

good morning, My 73 Duster has a bad repair job on the passenger door, i found a 74 door, are they interchangeable? i know that it will fit the car but im wondering about the inner workings of the door, is that the same as my 73? can i use the inner hardware and glass from my 73 and put it in the 74 door shell..thanks for any help and insight...Rich
