This is a Set (4 Piece) of Rally Center Caps for 1966 thru 1970 Chevrolet Full Size, Chevelle, Camaro, and Nova. This is a very nice set of original used GM caps There is some slight pitting on the "top hat" center. The correct "CHEVROLET MOTOR DIVISION" logo is on the upper surface as well as correct vertical ribs on the sides. See Pictures
