This cover was used with the Hydraulic lift mechanism that operated the Corvette Convertible Top. It has an extra bolt pad to accept the lift arm. It is in decent condition and will need to be sanded, primered and painted. If you want the 2 stainless mouldings add $300. Will trade for 1949-64 Oldsmobile or 1949-54 Cadillac 331 ci Engine parts & Speed Equipment. [email protected] 1 609 397-0161
