Please check notes in each part listing to ensure the Inner Fender is correct for your 1978 GMC K25 SUBURBAN with a 4.8L 292 engine. Special restrictions like "California only" or "with sport package" may indicate a Inner Fender fits only certain 1978 GMC K25 SUBURBAN models.

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

After choosing a Inner Fender, 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 Body-Exterior parts, other GMC K25 SUBURBAN 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 1978 GMC will not be lost if you switch.
