Please check notes in each part listing to ensure the Door Lock Cylinder is correct for your 1974 MERCURY MONTEGO MX with a 5.8L 351 4BBL engine. AIRTEX & STANDARD MOTOR PRODUCTS are competing brands, and each brand's Door Lock Cylinder may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Door Lock Cylinder fits only certain 1974 MERCURY MONTEGO MX models.

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

After choosing a Door Lock Cylinder, 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 MERCURY MONTEGO MX 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 1974 MERCURY will not be lost if you switch.
