Please check notes in each part listing to ensure the Differential Locker is correct for your 1965 CHEVROLET BISCAYNE with a 5.3L 327 engine. Special restrictions like "California only" or "with sport package" may indicate a Differential Locker fits only certain 1965 CHEVROLET BISCAYNE models.
Clicking a "More Info" link will display a picture and/or other details about that Differential Locker in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Differential Locker, 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 "Find More Parts" to find more Drivetrain parts, other CHEVROLET BISCAYNE parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1965 CHEVROLET will not be lost if you switch.
