Please check notes in each part listing to ensure the Truck Bed Side Step is correct for your 1966 CHEVROLET K20 PICKUP with a 4.1L 250 engine. Special restrictions like "California only" or "with sport package" may indicate a Truck Bed Side Step fits only certain 1966 CHEVROLET K20 PICKUP models.

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

After choosing a Truck Bed Side Step, 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 CHEVROLET K20 PICKUP 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 CHEVROLET will not be lost if you switch.
