Please check notes in each part listing to ensure the Connecting Rod Nut is correct for your 1980 FORD F-250 with a 4.9L 300 engine. PIONEER & DORMAN are competing brands, and each brand's Connecting Rod Nut may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Connecting Rod Nut fits only certain 1980 FORD F-250 models.
Clicking a "More Info" link will display a picture and/or other details about that Connecting Rod Nut in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Connecting Rod Nut, 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 Engine parts, other FORD F-250 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 1980 FORD will not be lost if you switch.
