Please check notes in each part listing to ensure the Back Up Lamp Socket is correct for your 1975 GMC P35 with a 7.4L 454 engine. Special restrictions like "California only" or "with sport package" may indicate a Back Up Lamp Socket fits only certain 1975 GMC P35 models.
Clicking a "More Info" link will display a picture and/or other details about that Back Up Lamp Socket in a separate window (you may need to turn off your pop-up-blocking software for this to work).
