289 HiPo Alternator Pulley. Steel with correct black finish.
Features part number C5AF-10A352-C stamped in face of pulley just like the original. Part number is stamped in a straight fashion-exactly like the original. This is the earlier style pulley that was used from the beginning of the 289 High Performance Mustang production (with alternator) to approximately May 1965 production.
This pulley also features the circular machining marks like the original.
We have looked at a lot of original pulleys, and it is very difficult to distinguish this pulley from an original.
