Please check notes in each part listing to ensure the Output Shaft Seal is correct for your 1984 CHEVROLET C10 PICKUP with a 5.0L 305 4BBL OHV engine. TIMKEN & NATIONAL are competing brands, and each brand's Output Shaft Seal may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Output Shaft Seal fits only certain 1984 CHEVROLET C10 PICKUP models.

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

After choosing a Output 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-Manual parts, other CHEVROLET C10 PICKUP 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 1984 CHEVROLET will not be lost if you switch.
