Please check notes in each part listing to ensure the Headlamp Socket is correct for your 1975 CHEVROLET C20 SUBURBAN with a 5.7L 350 4BBL OHV engine. DORMAN, STANDARD MOTOR PRODUCTS, & ACDELCO are competing brands, and each brand's Headlamp Socket may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Headlamp Socket fits only certain 1975 CHEVROLET C20 SUBURBAN models.

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

After choosing a Headlamp Socket, 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 Electrical-Lamp & Socket parts, other CHEVROLET C20 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 1975 CHEVROLET will not be lost if you switch.
