Thought I had something cooking with these, had sourced some ford emblems made for the center as well, but the clips were to fat to fit between the hub and the wheel.
Ended up going with Mr. Gasket 2486 dust caps, but they were smaller than they should have been by almost 2mm, took a cutoff wheel and cut some tabs in the back side and flared them out for a snug fit, had to pound them in with a hammer, hopefully they're road worthy. I'll post back in a couple months when I get this thing back going.
