I bought a set of Chrome AFS 17" FR500, 9" & 10.5", and they came with some black center caps that don't have anything on them. It doesn't look nice at all. I tried using my stock 03 Cobra rim center caps, with SVT on them, and they are too big. I think they are a different size from stock 17" rims and from 18" FR500?? What other ones fit and what are you guys running? I think I seen Cobravenom39 with black ones with a snake on them??? Where do I get those?
