Please check notes in each part listing to ensure the Flywheel is correct for your 1978 JEEP CJ7 with a 4.2L 258 engine. AMS AUTOMOTIVE & SACHS are competing brands, and each brand's Flywheel may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Flywheel fits only certain 1978 JEEP CJ7 models.
Clicking a "More Info" link will display a picture and/or other details about that Flywheel in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Flywheel, 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 JEEP CJ7 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 JEEP will not be lost if you switch.
