I did eventual solve the full wheel cover dilemma in two ways. 1) I located a fellow (through a number of sources) in Ca. whose dad had once had a cameo and had stored a set of the original wheels, and he was willing to see if he could find them and sell them to me. He found a full set of five! He blasted, primed, boxed, and sent them to me. What a guy!! In the meantime I had purchased Coker tires and smoothy wheels to accommodate a slightly larger radial tire. So I could use the full caps, I had a rod shop weld small nub beads, 4 on each of the smoothies, and they have worked just fine ever since. I still have the original "nubbed" wheels in boxes, in storage for future use if and when I decide to use them. This was all a long time ago. I am now well-informed, and well stocked with solutions to what was once a mystery. But thanks for sharing runningiron. I'm sure someone would be interested to know those rare types of wheels are still around somewhere. I know They are hard to find.
