It seems my underdrive pulleys were shipped with the wrong belts from CZP last year. It came with two Gates belts - K040365 - for the PS and AC. They are too long and max out the adjustments on the brackets. After looking it up, it seems these are stock belt sizes... Anyone know the proper length for PS & AC with an Unorthodox Underdrive pulley?
