Please check notes in each part listing to ensure the Convertible Top Seal is correct for your 1966 OLDSMOBILE CUTLASS with a 5.4L 330 engine. Special restrictions like "California only" or "with sport package" may indicate a Convertible Top Seal fits only certain 1966 OLDSMOBILE CUTLASS models.

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

After choosing a Convertible Top Seal, 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 OLDSMOBILE CUTLASS 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 1966 OLDSMOBILE will not be lost if you switch.
