I am switching my 62 hawk four-blade fan to a 6 or 7 blade fan. I have a fan clutch but not sure what clearance I should have between the tip of the fan blade and the shroud. Has anyone done this, and what fan did you use? It looks like a Mopar off a 318 will fit but not sure.

Hi,
The viscous coupling with a 6 blade fan isn't that objectionable unless your rear axle is numerically high. I had a straight 6 blade on my (3:31) Hawk and it was terrible. When I installed the viscous coupling, it dropped the noise to a very acceptable level.

Jon,
You need to take a trip to Royce City, out I-30 east, and see Bob Helm. He advertises in Turning Wheel, and has bought a out a lot of old dealerships. He had several tons of parts. He has saved mine, and several other people's bacon over the years. You need to call him at 214-537-0921, after 6:00PM central time. He probably has everything you need.
