there is two size belts for your truck. one for the 100, and 105 alternators and one for the 140 amp alternator. Can you read any numbers on the belt you have now?

napa shows the 100/105 amp alternator takes a NBH 25060960. (NBH is for Napa belt and hose)

for the 140 amp alternator it shows the NBH 25060966.

the part number gives a close description if the belt size.

the one ending with xxxxx960 is 96.01 inches in length. (2439mm)

the one ending withxxxxx966 is 96.61 inches in length. (2454mm)
