Small update, my steel got delayed but should be here tomorrow. I ordered the last of the pieces (I think) I ordered a clutch disc from RokAuto for a 94 Dodge truck, 1500, 318 v8, it's 26 bucks and then I ordered an idler sprocket for the back side of the chain (I was debating using one or not) it was $8.08 from The Big Bearing Store 
Once I get my 2x6x3/16 tube I will go to town on it. I was in town today and saw a buddies winch, I took some closeups of the brake, the mount and took some overall measurements. His drum is only about 5.5" wide but I think I am going to be OK with 8" drum. I was surprised to see how sharp of an angle the PTO shaft was with the winch in the air, I assume you aren't running it when the winch is lifted? I will have to remember not to. Oh that reminds me, I will have to buy a PTO shaft as I don't have one...lol
