273 non AC crank pulley

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?
