imfasternu2,
Been using power steering forever with the Ford pump. I love it!
My brackets are all home made except for the alternator, sorry. See my gallery for a photo or two - one of them is titled "dipstick" or something like that.
Here's a link to a relevant comment about the Saginaw pump, i.e., Fords have them too and probably they operate at the correct pressure:

Also, if you have a GM pump, there's a valve that's supposed to give the proper pressure:

The Saginaw pump is supposed to be better than the Ford pump. If you do end up with a Ford pump, ask me about the "Bondurant modification."
As a final thought, be
sure to put a cooler of some sort in the return line.
