ok so i am about to put the truck in the shop tomorrow to get my pulleys installed but i dont know if i have the right size belt.Herb101 sent me one with the #5 crank pulley but i am also adding a 2.8 upper so can i get away with just a 100mm idler kit because i believe the belt is for a #5 lower and stock upper so i thought there wouldnt be that much slack. any info will be greatly appreciated.
