    2.5-2.6: 672
    8 Rib NOTE: For these belts the part numbers are 080 rather than 060...or K8 with the Duralast rather than K6.

    the pulley is in the same place, the only question is..what size pulley. The chart should work fine for 3 or 5

    Sounds about right. The Gen V is really only bigger in length, not height.

    Does the chart on a 660 belt for 3.2-3.5 pulley mean a 60 " belt? Would my new Gates 060 be a 60 " belt ? Thanks
