This is a brand new in the box alternator for Ford cars and maybe trucks. Bought for a late 90’s to mid 2000’s Crown Victoria but the car was sold before installing. It will be an upgrade on mustangs by having more amps available. Has a lifetime guarantee and is a 135 amp unit with the oval connection. Asking $90.00 O.B.O. phone 712-737-3462 can pickup up in orange city or sioux center.
