This is a 3 groove crankshaft pulley which is correct for all 1965 and 1966 and 1967 Ford Mustangs   with or without power steering and with factory AC equipped with the 289 (alternator equipped) or 302  engine. Will not fit the early 289 or 260 generator equipped engines.    It is in good usable condition.     It is all original correct.   It is original Ford so it will fit and function just as Ford intended.   Great if you want to add accessory belts.    No import repro crap here!
