Crank pulley belt #

['72customdeluxe]

I was wondering how many slots does a normal '72 have on the bottom crank pulley with a/c and power steering. Mine has four, but the second to front is no longer used because the air pump is gone. The problem is that the power steering uses the very front slot. The supercharger kits I'm looking at call for a max of three crank pulley slots.. I don't want to lose power steering but will if I have to. Thanks
