Please check notes in each part listing to ensure the Differential Pinion Seal is correct for your 1957 PLYMOUTH PLAZA with a 4.9L 299 engine. Special restrictions like "California only" or "with sport package" may indicate a Differential Pinion Seal fits only certain 1957 PLYMOUTH PLAZA models.

Clicking a "More Info" link will display a picture and/or other details about that Differential Pinion Seal in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Differential Pinion Seal, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button, or click on "Find More Parts", to find more Drivetrain parts, other PLYMOUTH PLAZA parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1957 PLYMOUTH will not be lost if you switch.
