those are the center inserts for the "WIRE BASKET" wheels. I think Cragar made them in the late 70's thru early 80's. They're good for grilling hot dogs on the side if the road with. I had a set on an 80 Corvette years ago. They were that trashy Uni-Lug bolt pattern. Fit loosely & impossible to balance.
Not sure how I ended up with em, think they were in the bed of a parts donor '70 429GT Ranchero I used to have...
