I'm at the point for installing the Fan Clutch onto my 383 engine (71' Cuda- A/C car). When I got the car, the fan clutch was missing. I have a fan clutch off a 71' Charger 383 AC car, part number 3462107. I can't find any documentation on what I need, anyone know what came on 71 Cuda's 383 with AC? Many thanks!!!
