I've acquired a set of 8 1/2" x15" American Racing Wheels. They are straight spoke Aluminum with silver or no finish. The center cap area has no mount screw holes, so the caps would mount from behind with a bracket. They look something like Torque Thrust, but I'm beginning to wonder if they aren't a different model because of the center caps. Anyway, I'm looking for center caps for them. Originals would be best, but good-looking generic will hold me over. I can e-mail pics to clarify. Any info would help.
