This is a set of 4 of the plastic Wheel Cover Spinner Inserts for 1965 thru 1966 Corvettes. Note that there are two versions of this insert available. This version has a BLACK square in the upper corner of the right flag, while the other version has a WHITE square in the upper corner of the right flag. The flag squares changed during production (we carry both versions). If your Corvette will be judged, consult your judging manual before choosing. This is a Licensed GM Restoration Part and is sure to please!
