This is an NOS bezel. Looks like the normal bezel, but the pedistals where the screws go in are beveled to meet the cap. Price is $50 plus shipping. Part is located in NY.
Since it has the beveled inner edge it might be for a '67-'68 disc brake center cap (the one that is similar to a Chevrolet). I'll pull one apart and see if it has the bevel.
