Please check notes in each part listing to ensure the Power Window Motor Gear is correct for your 1974 MERCURY COLONY PARK with a 6.6L 400 engine. DORMAN & ACI are competing brands, and each brand's Power Window Motor Gear may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Power Window Motor Gear fits only certain 1974 MERCURY COLONY PARK models.
