Horizontal Mouldings with the tapeAre you talking about the door edge trim covers? The are on the back edge of the door and run vertically. If so, I've seen them in chrome and black and most stores, pep boys, AZ, etc have them.
Or are you talking door molding that runs don the side of the door horizontally? I pave seen Crome and black that stick on with tape and the Impalas had body color moldings.
