    This PML cover fits the GM 8.875 inch (8 7/8") ring gear 12 bolt differential for cars.

    Benefits:

    • Extra capacity
    • Drain hole and magnetic plug to simplify maintenance
    • Fins for heat dissipation and classic styling
    • Sand cast aluminum construction for thick walls
    • Machined gasket flange for a secure seal
    • Round shape similar to stock cover

    We have one of these on SPECIAL.

    This differential cover fits the rear end on the GM Corporation 8 7/8" (8.875") 12 bolt differentials used on many GM and Chevy cars in the 1960s and 1970s. Some vehicles which may be able to use this cover include:

    • Camaro 1967 to 1972
    • Chevelle 1965 to 1972
    • El Camino 1965 to 1972
    • Monte Carlo 1970 to 1972
    • Nova 1965 to 1967

    Always check to verify differential and clearance for a larger cover. Configurations vary. GM 8.2 inch ring gear 10 bolt differentials were also used on many of these vehicles. This cover is larger than stock so check space available.

    Oldsmobile cars in the 1960s and 1970s may have a similar looking 12 bolt rear differential cover. Oldsmobile offered a similar differential for such vehicles as the 442 and Cutlass. The differential cover for these applications is about 1/4 inch different than this one. PML does not make a cover for these Oldsmobile differentials.

    Cadillac also made their own differentials for some of their cars.
