Demon Dart Sport door glass interchangeable?
I would think with some mods you could make it work. Don't know that the regs are much different or not. I do know they changed where they are at in the door. 73+ is up higher than the 72 down window regs and I would think they would have had to change the window trackes a little to do that.
I have a 75 Duster with out the door panel on it I can get a pic of for you just so you can see the differences.
