Mr.1984

guys I need some help i am removing my air pump and A/c compressor from my 84. I already have the condenser off and my coolant hose connected from the intake to the water pump.I also know that the ac braket can be used to mount the alternator and to get a 85 ps fluid resivoir. The only thing i can come up with is replacing the water pump pulley with a 6 ribbed pulley and routing it over the alternator over the water pump under the crank over the ps pump and back to the alternator will this work if so where can i get a 6 ribbed water pump pulley that will fit?
