6.1 no p/steering no a/c pulley
Kinda' late to this thread, but I did this with a truck cover and stock pulleys plus 1 added. The only difference with mine is that all my builds use cs130 alternators so that mount would be different (not modified). If you don't want to cut up the TC casting, you don't have to. I did for weight and appearance. I found an OE idler pulley centering base (they usually come of with the idler when replacing one) and bought a grooved idler pulley. I turned down the protruding, internally threaded boss at the upper right of the water pump and installed the pulley. Use the OE pulley bolts. Luckily no spacing was needed but it is simple to do. Been driving it, and down the track already with no issues. Oh yeah, 6.1 block,6.4bge heads and '04 truck 5.7 TC. My belt length wouldn't help you though.
