I believe those would have been the upgraded PO3 caps (standard would have been painted), and I also think the centers (the concave circle that contains the "gmc") is supposed to be black. But, yes, correct caps for 69-72 1/2 ton truck that had the PO3 hub cap option. These may also be from 73+. Anyway, they are for 15" wheels (steelies) - confirm by measuring the diameter, should be 10.5" approx. IF (and I can't quite tell in the pic) they are 12"-ish, then they are for 3/4 ton 16" and 16.5" wheels.
