My panels are for my 74 cuda. There is a big difference between cuda and challenger panels. As for the color, it is molded into the plastic I don't think that it is white over black.From what I saw when they molded these doors there were blue inpurities in the plastic that accounts for the marks that I have in the doors.But I don't understand why they did'nt check the product before they were shipped out!! And the way they are handling the replacement situation, does'nt say much for their customer service!!
