Probably know but take a pair of pliers and bend the "teeth" on those hub caps out a little more. The caps will be a bit harder to get on but also a lot harder to come off. One of the first signs that the cap is too loose is that it will "walk" around the wheel. You'll notice it when you go to check the air pressure and the valve stem is no longer lined up with the hole.
I made some wire caps from 14 inch Chevy (
) wire hubcaps trying to copy the Kelsey Hayes wire wheels - added the 3 bar Tbird spinner in the center. Still deciding if I like them - may switch back to original and put the optional Red/White/Blue sun ray trim in the center.

Mine was a late production '60. Sounds like we're just cousins rather than twins.
