While we are probably best known as the 12 Bolt "O" Axle specialists, we also carry an extensive selection of rear end components for all 64-76 Cutlass/4-4-2 differentials. All are of course premium grade products proven that they can handle the torque of a Big Block Olds. For ordering, you will need to know which differential your car is equipped with. For identification, see our Diff ID section If you have any questions, just call our tech line at 503-641-1442 M-F 10-5 Pacific Time. Remember, "Anti-Spin" is Oldsmospeak for "posi", "posi-traction", "limited slip", etc.
