I'm planning on taking the A/C unit and possibly the power steering out of the TGP as well as going with the FFP underdrive pulley. Does anybody know where I could get a serpentine belt that would fit after I pull this stuff off?
All the auto places should have belts that fit. You just need to measure how long you need the belt. ie if you need a 65 inch belt ask for a 650K6, 65.0 inches long with 6 ribs.
You can also order any size belt you want from Summit. I always get the Gatorback belts and IIRC the last 3 digits of the part number are the length of the belt.
