Actually, that's not the right way to adjust the pressure of the P/S pump.
You pull the high pressure hose, remove the big nut that it goes into, then
pull out the spring and the little valve that is in there. When you look at
this valve you will see that there is a nut on one end. You must carefully
secure the valve in a vise and remove the little nut, being real cautious
not to damage the valve or it's machined surfaces in any way. Once you get
the nut off, you'll find that there are one or more thin washers under this
nut. These washers are what determines the pressure output of the pump. Add
washers to decrease pressure, and improve road feel, take away washers to
increase pressure, and remove road feel. You can get washers from any
Saginaw P/S pump, be it the old (4 bolt cover) or the new (snap ring cover)
style. The washers are all the same.

Jim,
I did that swap on my previous Bird with very good result and will definetly
do it to my new Bird as well.
I used a gear box from a '84 or '87 GTA (can't really remember what year it
was) and it bolted right in.
You will need a new rag joint though. It can be found in the "HELP" section
at your local dealer or use the one from the donor car. You also need custom
made hoses or the now available adaptors that companies like detroit speed &
engineering sells.
I didn't have any problems with steering stroke beeing limited, be prepared
to see an increase in steering effort though.
The steering gets quite heavy but can be controlled by stretching a spring
in the steering pump outlet port which controls the preassure in the line,
or get the spring from the donor car. To me it was never such a big problem
that I bothered to stretch that spring.
Here's a link on the subject:

While my 69 is apart I was going to pull the power steering box and have it
rebuilt. I've seen messages from people saying the newer boxes are much
better. I'm wondering if I should buy a 92 IROC box and have that rebuilt
instead. I understand it's a direct bolt on. Will the hose ends need to be
changed? When I talked to the local PS box re-builder about putting an IROC
box on my S-10 he said they would have to redo the internal stops inside the
box or I would not be able to turn the wheels all the way to the frame stops
and the turning circle would be much bigger. Has anyone who has swapped
noticed that being an issue?
