I started bolting on my supercharger today and i ran into a problem. The idler pulley that they give you that bolt to the triangle on the bracket is hitting the Alternator when i bolt the bracket on to the motor. I am not sure if they gave me the right pulley. The one that they gave me is a 76mm Flat with a flange. The one they show in the instruction manuel is a flat pulley with no flange. The flange is what is hitting the alternator. Could some check what pulley they have and a part#. Thanks for they help!
