Thanks for the Demon kit guys! it came really fast. Now that I have it I'm comparing it to the 71 Duster kit, and I think I can put the Duster frame, engine and interior into that Demon body without too much problems. They are, after all, the same car. (PICS)
The only thing Dodge did was to put the dart front end on the Duster body. Made it look more sporty.
