I have swapped out some aluminum wheels for my stock steelies. The guy I bought the aluminum wheels from said the came off of a GM class C and as they're an exact duplicate specs-wise from my stock truck wheels (6.5Jx16 ET13) I tossed them on. The center caps were gone, but the seller said the wheels had been stock on the Class C. I had never seen the logo on the caps before and after looking for a few days, couldn't find any manufacturer or brand that came close, so I have to assume he was right.

Anyone know what these are, or who made them? I'd like to get those center caps.
