Denny,
Sounds like 3/8" is the height that worked for you. And hopefully it'll get me close. But you had to put holes in the clips you got from vendors? I had bought a few from Jim Carter Truck Parts to try and they are shorter. The hub caps that I'm using are 55-56 Chevy 3600. Problem now is I need 16-20 of them for 4 wheels. Maybe I could find something like steel spacers from Granger or Mcmaster-carr type supply house?
