shorter clutch fan

Try the hayden #2765 - This is the one I used on my car....'65 Cuda

Installed with a 3 core U.S. Radiator Optima core...Aluminum March Performance pully.
Was a bit tight but took the pully and clutch to machine shop and had 1/8" milled from face of pully & 1/8" milled off leading edges of clutch heat sinks.
Now have 5/8" rad to clutch.
