It's simple. Just pull all the AC stuff (compressor, condenser, lines, etc.). Leave the evap/expansion valve unless you plan on pulling dash to remove it. For the power steering, just pull the pump and high pressure hose. Plug it at the rack. You can leave the return hose and reservoir if you plan to ever go back and want to put fluid in the rack easily or just pull and plug that too.
Then all you need is a VR6 water pump pulley and a 6PK1033 or 1035 belt to run everything off single serp belt. You may get flack from people here about no power steering with a power rack. It's really not that bad. I've had mine like this for 2 years and no problems. I did not loop the lines or anything on the rack and left return hose and reservoir.
Please take it to a shop to drain AC refrigerant unless it's already empty.
