Rear End Differential Cover – GM Passenger Car 12-Bolt – 1965–1972 Chevelle El Camino Malibu, 1967–1970 Camaro Firebird, 1968–1971 Chevy II Nova, 1970–1972 Monte Carlo, 1965–1970 Full-Size Chevrolet | OE-Style Stamped Steel | GM Part #3976857
Restore the original appearance of your classic GM muscle car with this OE-style Rear End Differential Cover for GM passenger car 12-bolt rear axles. This high-quality reproduction fits 1965–1972 Chevrolet Chevelle, Malibu, and El Camino, 1967–1970 Camaro, 1967–1970 Firebird, 1968–1971 Chevy II and Nova, 1970–1972 Monte Carlo, and 1965–1970 full-size Chevrolet passenger cars equipped with the factory passenger car 12-bolt differential.
Manufactured from heavy-gauge stamped steel just like the original GM component, this reproduction faithfully duplicates the factory-installed cover, including the correct smooth lower edge without the notch found on later GM service replacement covers. Engineered to OE specifications, it features the proper contours, bolt pattern, and sealing surface for an authentic factory appearance and dependable fit.
Replacing a damaged, rusted, or dented differential cover helps protect the ring and pinion gears, bearings, and differential assembly from contamination while maintaining proper lubricant retention. This reproduction is an excellent choice for concours restorations, factory-correct muscle car builds, or replacing a worn original housing cover.
This is an Officially Licensed GM Restoration Part and replaces original GM Part #3976857 (GM Group #5.398).
