I would like to convert my 85 4x4 to power steering. Is there any websites with a write-up?

Can I use 2WD reservoir, hoses and pump, brackets? I know I will need to find a SAF power steering box can I use one off an early 80-83 truck?

What years of parts can I interchange?

 

I will be doing the same thing to my truck also (I have an 85 also), i got a complete power steering pump/reservor all hoses and mounting brackets from an 89 2 wheel drive pick up, it will bolt up to the factory location, im doing my lift soon and adding high steer so i will be getting an ifs steering box, and as far as i know the hoses will screw on to the ifs steering box.
