as far puttinf power steering on yours, you could box the frame where th steering box mounts, find a 70's chevy (insert just about any chevy with power steering and 305.. maybe any V8) grab the pump, mounting bracket, resivor, and steeing box off it, and install it. Chevy vehicles should all have the Sagniaw steering box. then take teh fitting on each end of the hoses to a hydraulic store and have them make some hoses for you that would match CJ power steering hoses. you'll hve to come out from under the radiator which is pretty tight area.
really shouldn't be that bad to do. I did the same thing on my CJ but pulled mine from a waggy witha V8 and got the moutning bracket, pump, resivoir, hoses, steering box and drag link for like $120 some minor alterations and replacement parts and it's been running great since.
