Ford part numbers will include "12a650" in the body of the original equipment part number printed on a sticker on the unit. For GM, check the "service number" sticker. Chrysler part numbers will start with at "P" or a "PN" and will be printed on a sticker on the unit. If you can't find the Part Number, use the search above, call a dealer, or contact us for assistance.
