Please check notes in each part listing to ensure the Crankshaft Seal is correct for your 1963 FORD 300 with a 7.0L 427 engine. NATIONAL & FEL-PRO are competing brands, and each brand's Crankshaft Seal may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Crankshaft Seal fits only certain 1963 FORD 300 models.

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

After choosing a Crankshaft 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 Engine parts, other FORD 300 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 1963 FORD will not be lost if you switch.
