fan noise

[tankrat7.3]

While I was changing the belt on my 99 I noticed a fan clutch bolt had started to back out. While I was tightening it I noticed one was missing. Now it sounds like the fan is hitting something when the engine is r running. I spun it by hand and didn't notice the blades hitting anything. My question is do you think just putting a bolt in might fix it or should I just change out the whole clutch?

I bought this truck about a month ago and have already changed both batteries, alternator, fuel filter, vacuum pump, and belt.

Never mind the truck answered that question for me when the water pump pulley shreded the bolts and now i am replacing all of it.
