Nice car. Wheels are really in the eye of the beholder, like wide or pinner whitewalls. You might start over at Wheelsmith for ideas. The vintage and smoothie categories. The old standby in the mid fiftys would probably been different hubcaps. Lancers, flippers, moons or baby moons, trim rings. Up to you. Theres a social group here that might also have some ideas or pictures. Still got the 239?
