NotesThis is a Ford 4GHO Alternator (Later Style Using the 6G Stator) for the 2001-03 Ford Mustang With the 4.6L (DOHC) Engine. This Looks Very Much Like the 7781 Used Earlier. The Pulley May Also Be Larger (Diameter) Than the Previous Version. | This is a Ford 4G Alternator. This Looks Like the 7773, Except That the Mounting Holes are "Open" Rather Than "Closed", and This Uses a Different Voltage Regulator. According to Ford, the Front Mounting of the 7773 and the 7781 Interchange, Despite Their Appearance.
