Please check notes in each part listing to ensure the Door Seal / Weatherstrip is correct for your 1978 GMC C25 PICKUP with a 5.7L 350 4BBL OHV engine. VARIOUS MFR, FAIRCHILD, SHERMAN, & METRO are competing brands, and each brand's Door Seal / Weatherstrip may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Door Seal / Weatherstrip fits only certain 1978 GMC C25 PICKUP models.
Clicking a "More Info" link will display a picture and/or other details about that Door Seal / Weatherstrip in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Door Seal / Weatherstrip, 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 C25 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 1978 GMC will not be lost if you switch.
