has anyone ever used these or seen them . will not fit on a 40 wheel or wide 5 not deep enough. looks like they may fit over the center to hold them on? maybe for a wire wheel? maybe a wire or
Ford F-250’s did this for a few years in the 70’s and used the 1955-6 car wheel disc on the adapters which I believe were used on the 16.5 rims. Top of the line “Lariat” at the time had them if you checked that box..
mid 80's chevy 3/4 ton trucks used 16"wheels with adapters to 15" caps. I've only seen a few sets tho.
I thought these were old never thought of 70s 80s pickup trucks. looks like they would need a pretty wide wheel or a lot of offset
