Please check notes in each part listing to ensure the Alternator / Generator Rectifier is correct for your 1975 MERCURY MONARCH with a 5.8L 351 engine. BWD/NIEHOFF & AIRTEX are competing brands, and each brand's Alternator / Generator Rectifier may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Alternator / Generator Rectifier fits only certain 1975 MERCURY MONARCH models.
Clicking a "More Info" link will display a picture and/or other details about that Alternator / Generator Rectifier in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Alternator / Generator Rectifier, 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 Electrical parts, other MERCURY MONARCH 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 1975 MERCURY will not be lost if you switch.
