Thom, I took a picture of mine today. They are not bolted together but you can see that I like the same sort of hubcap that you do. Mine were on a '69 LTD, [in fact that's the hood for a background] and the spinners are probably off a '56 Oldsmobile. I really like spinners; so keep up the good ideas.
Two are going on the front of a '46 Dodge coupe and two on the front of a '50 Ford chopped coupe. Both cars will be taildraggers and have fender skirts on the back.
