magnum power steering pump with serpentine belt adapted to 73 power steering box?

Here's what I did on mine:
Mini Update: Fuel Line Wrap, Power Steering Line and Seat Spacers

I used the Grand Cherokee set up and it has no clearance issues with the battery tray.

Hey @dartslantsix I was wondering, are you running an A/C compressor or an A/C delete pulley in your setup?

I know someone that is trying to the run the Magnum serpentine setup but without and A/C compressor OR A/C delete pulley while using the Cherokee power steering pump. He needed help trying to figure out a part number for the correct length belt. Can you help in situation? Do you happen to know the correct length and/or part number for a belt? Thanks!
