Matt, that fan clutch and big fan will never work in that truck. The fan blades will want to be right where the radiator hose absolutely has to be. That is the majority of your clearance problem you have to loose the fan clutch and fan and run a fan that is a smaller diameter and just bolts to the water pump hub with a proper thickness spacer if it needs a spacer. That alone should get you several inches of clearance. The clutch alone is taking up three or four inches in front of the water pump pulley.

Remove the fan and clutch and do some measuring.

You need to know how much room you have between the hose and the center of the water pump before buying a fan though. I'd want at least and inch of clearance. I had the same problem with my truck in that I had to buy a smaller fan.
