A few yrs back, I bought a ps kit from a shyster in Iowa. (Didnt know he was til I got the box full of parts). Was for my '72 F100. Put it all together, and the pump whined like heck. Sounded like it had sand in it. So called him,and he reimbursed cost of rebuilt pump. Changed fluid again. Then a month later, steering box started leaking. Called him again, and couldnt get him to call back after several tries. Went to store, bought another one, put it on, and changed fluid again. Looked to me that he went to the junkyard, found what I needed, and sprayed a nice coat of black paint on everything. The wrapping paper in the box was partially stuck to the sticky paint. One of these days, when I get back to that neck of the woods, I'm going to look him up.
