Evidently there is only one manufacturer of the repop flip top Challenger gas cap cover. I have received two units (Year One) and on both units the chrome cap does not rest parallel to the black base (hope I'm describing that right). As a result, the part looks totally stupid when on the car. Year One, as usual, has been really great about handling the problem. If you place the repop unit on a table next to an original, the difference is huge. I'm not optimistic about obtaining a satisfactory unit so am thinking about getting mine rechromed, except it is impossible to take it apart. Anyone else had problems with these units? Has anyone had the entire assembly rechromed, base and all?
