Lets play, "Name that Hubcap!" again

[rideblue00]

So looking to I.D. this cap. Have no idea what its from, but it has the 1966 raised outline around the 3 points like all the 66 truck caps do. The chrome on in my pic is the standard 66c10 cap. You guys proly know the dimensions already. So the dims on the white one are 9 5/8 o.d. 9 1/8 i.d. and its side height is less than 3/4. I have been googling pics for months to no avail. Dont know why I didnt just post here first. Any ideas? I thought they might be for a G10 van but not sure. I bought them sight unseen from a friend and paid way too much. I need to identify them before reselling. Any info would be greatly appreciated!
