I used the PS pump and Hydroboost from a 78 Lincoln Town Car. This pump is a saginaw pump with two returns. On my 5.0 HO I used the PS pump bracket from a 91? Ford E-350 which had a 351 5.8L engine. I had to grind quite a bit of the bracket's out side circumference to clearance the PS gearbox. It works very well. I also installed a radiator with the hose attactments set up for a 5.0 conversion. This places the lower hose very close to the the PS pulley. I could not find a single hose that attaches to the water pump and to the lower radiator, so I used ends from two hoses and joined them with a piece of aluminum tubing. Since the PS pulley was very close to the lower hose, I had a custom pulley made to about 4 1/2" diameter and had it cut for a 6 rib serp. belt. It all works. The steering is so much better and the braking assit is much greater. This is a worthy modification. Good Luck
