I got rid of the LB7 alternator bracket & went with a LLY bracket
looks like the tensioner & one of the idlers is in a different location on the LLY
the truck has a 130amp alternator
previous belt GOODYEAR Part # 4061182 Gatorback; 6 Ribs / Effective Length 118.264" / Outside Length 119"
new belt GOODYEAR Part # 4061203 Gatorback; Poly-V; 6 Ribs / Effective Length 120.375" / Outside Length 121"
