1971 demon and 1976 duster parts interchangeability

Guys,
I am picking up a 1976 duster next weekend and want to know if any of the following parts will interchange?

Quarter panels
center of trunk where spare goes
doors


The trunk is the only part that is the same. The 1/4 will work but will need the side markers and the back where the bumper bolts on reworked a bit to make it exactly the same. The doors will bolt on but that is about it. The glass is different and there will be a gap at the window and the iner part of the door is very different as well.
