What door years will fit a 69 Dart?

I would think to try a 70-72 door to see if they would match...
That's what I was thinking but I'm not sure if they said the same armrest and interior door handle as a 69. I saw a couple at the Nat's this weekend but the door handle was different and in a different location. I wasn't sure what year they were or if the entire door was the same and back in the 70s if they just designed the interior features to work and bolt in in different locations on the same inner door frame
