It had a hitachi alternator on it from a previous owner, and my rebuild shop just handed me a 'will-fit' replacement they had collecting dust on the shelf. Was an old unit, evidenced by it needing an old style external mechanical regulator... Any good alt/genny/starter shop should be able to come up with something with the right mounting ears, pulley, and regulator.
Sorry, but my unit has no number on it that I can find.
