Back in the day some of you will remember, there were aluminum full size "discs" made popular on cars that raced at Bonneville salt flats. A lot of guys used them on street rods and sometimes drag racing. They were attached with screws and made by the Moon co. I believe was in So. Calif. of course. In 1961, I had a 57 Chevy with small chrome "baby moons". They have been popular a long time. Steve
