Are Duster and Scamp doors the same?
Well, I can try. On mine (74 Scamp) it has the normal inner door panel, but then at the top, where other cars have metal that extends from where the window goes, down to meet the regular inner door panel, mine is some kind of plastic or heavy vinyl material. If you rolled the window down, and layed your arm on the top of the door (you know, to look "cool" - hehehe), thats the part that is plastic and it extends down to meet the regular door panel. :|
