Please check notes in each part listing to ensure the Clutch Fork is correct for your 1978 GMC C15 SUBURBAN with a 4.1L 250 engine. RHINOPAC / WORLD CAR, ATP, ACDELCO, & DORMAN are competing brands, and each brand's Clutch Fork may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Clutch Fork fits only certain 1978 GMC C15 SUBURBAN models.

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

After choosing a Clutch Fork, 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 "Find More Parts" to find more Transmission-Manual parts, other GMC C15 SUBURBAN parts or parts for a different vehicle. Please try our Interactive Catalog (click link 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.
