I'd give Jim Carter a call -direct. See what he might have for used caps. There was also a big hubcap place in the Northwest-Oregon or Wash. State IIRC. You could also go with regular caps and hole out the centers like the early 4x4's did for their front caps. No logos. Have you tried a 1/2 ton cap on the 3/4T wheel without it being mounted to the axle? Would it fit? Or is it too small? If you can't find any, I'm sure that truck will still look very tough with super clean rims, new lugnuts, painted axle ends and no caps. Some of the early GM literature for corporate 4x4's show new trucks without hubcaps. Some 1960 lit. I have comes to mind.
