Please check notes in each part listing to ensure the Differential Bearing and Seal Kit is correct for your 1964 DODGE W300 SERIES with a 3.7L 3687cc 225 engine. NATIONAL & TIMKEN are competing brands, and each brand's Differential Bearing and Seal Kit may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Differential Bearing and Seal Kit fits only certain 1964 DODGE W300 SERIES models.

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

After choosing a Differential Bearing and Seal Kit, 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 DODGE W300 SERIES 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 1964 DODGE will not be lost if you switch.
