Please check notes in each part listing to ensure the Shift Shaft Seal is correct for your 1977 FORD F-250 with a 4.9L 300 1BBL OHV engine. SKF, NATIONAL, & TIMKEN are competing brands, and each brand's Shift Shaft Seal may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Shift Shaft Seal fits only certain 1977 FORD F-250 models.

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

After choosing a Shift Shaft 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 Transmission-Automatic parts, other FORD F-250 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 1977 FORD will not be lost if you switch.
