Please check notes in each part listing to ensure the Tail Lamp Assembly is correct for your 1978 GMC C15 SUBURBAN with a 5.7L 350 engine. Special restrictions like "California only" or "with sport package" may indicate a Tail Lamp Assembly fits only certain 1978 GMC C15 SUBURBAN models.
Clicking a "More Info" link will display a picture and/or other details about that Tail Lamp Assembly in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Tail Lamp Assembly, 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 C15 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.
