I found a guy who has a set of really nice 70 Challenger door shells, and I want to use them on my 73. I have to pick them up within the next day or two, so I need a quick answer. I just want to make sure that all of the internal stuff (window tracks, lock mechanisms, etc) will all transfer over from my doors. I think everything should work, but I'd feel a lot better if I got the word from some experts. Also, is there anything I should watch out for, internally? They are rust and bondo free because they came from a western car. Thanks
