Update - obtained a used CUCV power steering unit and rebuilt it. Ordered the USA-made Delphi pump from PSE. Popped out the used pump, cleaned everything, and then installed the new pump into the reservoir tank. If you plan to do this, make certain that you clean off all the old paint, rust, etc from the perimeter of the old pump rim. I took a piece of Scotch-brite and polished the landing surface of the old reservoir, as any foreign anything will result in a leak. I greased the new o-ring around the new pump, and also smeared a little grease around the 3 sealing washers on the back of the new pump which seals the pump to the back of the reservoir. Getting the new pump to snap into the reservoir was a little tricky at first, but then I used a pair of deep throat Vice Grips and pressed it all the way in. Made sure the 3 back sealing washers were still in place and then installed the back bolts and pressure fitting. Taped up all the sensitive areas and bead-blasted the whole thing, and then shot some engine black paint on it. Once I figured everything out, it was pretty easy. The large bracket must be re-installed onto the new pump before the pulley can be pressed on. You must use a special power steering pump puller/press to install the pulley. I bought one on Amazon and it worked like a champ to get the original pulley off and then press it back on the new pump. A word of caution - when reinstalling the assembly back onto the engine, make certain the power steering pulley aligns with the crankcase and water pump pulleys. I had to add a washer behind the adjusting bolt closest to the crankcase pulley to make these align. I suppose that may be the reason people are wearing out belts so often, and maybe the reason for squealing belts. I took a straight edge and calipers and mic'ed the distance and sure nuff, had to add a washer. Now they are all aligned. Here are a few photos -
