power steering to manual steering a-body help

I have a 73 Duster with a 318 that I went from power steering to manual steering. The car has factory air conditioning. The fan belt used to go around the power steering pump. Now I have no way to adjust the fan belt. I cannot find a 318 with air and manual steering to rob a bracket/pulley setup from. Any suggestions. Does someone make an aftermarket setup for this?
