Demon door?? Which others fit?
Ok, so I labeled some pictures to show the differences between my '71 Duster doors and '72 Dart doors.
Here's the inside of the door shell. You can see that the door frame stamping is identical. The red arrows on the duster door show the bolts for mounting the Duster window mechanism. All of the bolts go straight into the mechanism, so the door frame would just get holes drilled-easy. Not so easy are the internal brackets that are used for mounting the window guides in the Duster/Demon door. I highlighted their locations with the dotted lines (you can see the spot welds inside the edges of the dotted lines, it's a lot more obvious in person). The brackets are different between the two doors. If you wanted to make a Dart door into a Duster door, you would have to either fabricate the brackets to mount the tops of the window guides, or remove them from another Duster/Demon door. To do the opposite, you would have to fabricate the bracket for the vent window. The vent window bracket is pretty simple, it's in a later picture. The brackets would be the biggest headache.
