With this pulley I've also started recessing the belt grooves .03 inches so that there are flanges on the sides of the belts to make sure they don't walk.

4 pieces with two different size drives for the supercharger belt.


Starting with the alternator drive face down, the smaller choice of supercharger drives stacked onto it.


Then the spindle stacked onto that.


Then the ac drive stacked onto that.
