Motorcraft Ford 15V 55A D30F 10300 BA NEG Alternator. Obtained when I purchased some of the inventory of a small town hardware store in Sandersville, Georgia, that was being liquidated. It had a price tag on it, but I lost the tag when moving the alternator; the plastic piece it was on is still on it, though, that the tag was on. Guaranteed or your money back. Was in storage in the back warehouse part of the hardware store for a long time. Thank you for your interest.
