Power Steering

Hi, I have a 110, ex-army 3.5 V8 which I have as a first project. The engine sounds great, it doesn't have power steering, it is a heavy thing!! I have visited a 4x4 dismantler locally today and looked at the existing defenders, all the power steering units had been taken. Could anyone please tell me if I could take the system out of a 200/300Tdi Discovery and correct me to what I would require? Pump, pulley, steering box, reservoir..... Many thanks

Mine has no PAS, works ok for me!
