This is an exhaust valve for many different GM vehicles from 1965-1981. This is for Chevrolet Camaro, Corvette, and Chevelle vehicles. This is a brand new, factory OEM, genuine GM part, still in the original box. This box is in really bad shape, but the valve is in great condition. This is for one valve only.
