That site tells you the pump pressure they use. I know how to get close with parts I already have. I have to buy another pressure hose. It comes with the adapter so I can use the early control valve or later control valve

Once I get the hose I will post a part number. The parts store I use is real savvy on steering. They have a real thick steering book. They told me about changing the seats for o ring hoses. The steering boxes were already put together before I found out. I found out about the hose online. Its too late for the O ring hose even though one quick box is being used for one already set up for O ring hoses. The new pressure hose is cheaper than messing with all the other options

They tell you how to change the pump pressure in www.gmtruckcentral.com and Hemmings Motor News websites. I might be able to just use the 65 control valve as is for more road feel.

gmtruckcentral shows you how to tell the pump pressure by the height of the flow piston. You need more than one flow piston to compare them. The Motor Manual shows the pump pressure by make and year. As long as you know the origin of the power steering pump that should work. If you get a random power steering pump then it might not work.

"I can't find an adapter for the later style pressure hose to the early style housing so I have to use a early hose and swap the fitting on the pump to use it. "
I ran into the same problem putting a 1979 WS 6 box in my '70 bird.
GM switched from double flare fittings on power steering & A/C systems to what is referred to a "BUMP TUBE" fittings that use a Viton O-ring seal instead of traditional inverted double flare type fitting (anything to save a step in production).
There are adapters available on certain sites. I'll dig up the link (if I can find it) and post it.
Instead of resorting to that I found a Dorman/Motormite HELP card rack at Autozone that had a length of steel fuel or AC line that had the right diameter Bump Tube end on it & cut off a short section with the tubing end on it and attached it to the steering box then mated the stub end to the cutoff end of thev1970 pump line with a SWAGE-LOK coupling for that tube dia. Works fine ( Swage-Lok or Yor-Loc compression fittings are much better for higher pressures than standard compression tube fittings & they will not crush or distort the tubing when tightened).Use a good tubing cutter & Just be sure to ream/ de-burr the cut ends of the tubing and blow them clear.The box is more responsive and if yer doping of at the wheel it will get your attention but it is not that radical of a change. Ya just gotta learn the new steering inputs for the car. Less is more.

The first picture from left to right. 65 Tempest flow piston, 70 Lemans flow piston and 73GP SJ flow piston. The second picture from left to right, 65 Tempest flow piston and unkown flow piston. If you go to gmtruckcentral.com and look under articles you will be able to tell the power steering pump pressure by the height of the flow piston and if it uses washers.

When I put the 65 power steering box together I used a 65 pitman shaft, and the rack piston and worm gear from the WS6. If I changed the pitman shaft to the GJ or WS6 it should change the steering ratio. The last picture is the 65 pitman shaft.

I removed the pitman shaft from a 73 GP steering box. The teeth are tall like the teeth on the GC pitman shaft. The side teeth are completely different than the other pitman shafts. The teeth on the rack piston are also different. The GC pitman shaft won't fit into the GP housing because the teeth are mismatched.

I have a few of the 900-1000 psi flow pistons, according to the GM truck site, that is the lowest psi factory flow pistons. The second steering box I put together is tighter than the first if you turn it by hand. The first steering box is not as tight because I used the 65 pitman shaft and I think the teeth are not machined to be as tight.

What car are you putting this box in?

Don't know yet. Maybe the wagon. I have a ST10 that might go into it also. I will see how motivated I am when the weather cools down. If the first steering box goes into the wagon I am leaving the stock flow piston in it. The second steering box is getting used first.

The second steering box is replacing a 605 steering box. The 605 steering box had easy to turn steering when it worked, it had a lot of assist. When a 605 steering box stops working right its really hard to steer when the pump is unhooked. Forget driving it when it does not work. The Saginaw 800 steering boxes use a different pitman arm than the 605 steering box. I think I might have the right pitman arm but I won't know until I install the quick box.

The first picture GC pitman arm on the left and 73 GP pitman arm on the right. In the second picture you can see the codes on top of the pitman arm teeth. In the last picture you can see the 73 GP rack piston.
