Serpentine belt broke and is missing. I need to know what belt to purchase. My truck uses 2 belts, the A/C is separate. I purchased a 93 inch belt. It is too long.

The VIN is 2GCEK19TX21401601
If this will help.

There are 2 possible belts for that vehicle. The difference is if you have the heavy duty alternator option. The base 105 amp alternator takes a 92.25" # 6K923 while the 130 amp unit uses the 93.75" inch # 6K930 (I suspect this is the one you have) The belt routing is still the same but the larger alternator has a slightly larger pulley on it.
