If that "rubberized" crank pulley is in good shape, you definitely don't want to damage it. They're getting pretty hard to find these days. I'd either get a non-A/C pulley, or get the correct stock fan and spacer so it doesn't hit the existing pulley. Sounds like you need a 2 groove....one for the alternator and water pump, and the other for P/S?
We have the stock AC fan and shroud. And the rubber "dampened" pulley will go in the huge "AC for '66 Cuda" box in the loft for when everyone grows up and thinks its hot in the car.
We were putting the 5 blade MP clutch fan on to free up some HP in our quest for 12's.
