This is a custom pulley we machined to fit between two Ford OEM pulley pieces. Our customers alternator has a two groove pulley but his original pulley setup on the engine only had one groove. So he asked us to machine a single groove pulley that would fit in the space between the leading AC belt groove & the alternator belt groove so he can utilize two alternator belts.
