Harmonic balancer and water pump pullies

The harmonic balancer is the same as non AC application. There is a stamped steel pulley that bolts to the back (engine) side of the damper for the AC. The PS pulley bolts to the front of the damper. What aftermarket compressor mount and drive are you using? In the OEM configuration, the dual water pump pulley is not required. It makes things better as it helps with belt whip but is not required. Just about all the aftermarket mount and drive kits include an ac pulley that bolts onto the front of the damper, but that opens a can of worms as for clearance.
The pullies are the hurdle, all of the aftermarket ac companies do not offer or know where to get the bolt on pullies or water pump pully. I found one guy in CA.that has used ones.
