I have a set of Gragar SS on my 74 duster, drums all the way around. They are 15" with 5X4" (SBP), these were special order from Cragar. I'm thinking about doing a brake swap and switching to BBP if I can sell these wheels easily. The question, should I be able to sell these wheels quickly and easily or should I just keep them on and forget about it? Before you ask, they are in good shape, not brand new but good shape.
