Thanks for that info. I see several different pitman arms. I'll have to think this over. I've been kicking this idea around for a few years now.
I think at the very least, we've given the OP something to work with.

 

Agreed. I like when oddball projects like this come up. 99% of the threads here can be answered with "buy an FSM and do what it says". It's really interesting how much can be learned by accepting the possibility of a bad result and just doing something cuz you feel like it *could* be done- and to watch, and help, others go through the same process.

 

I decided to rebuild my column and go w/ blue top gear and replace C2 pump with Saginaw pump and possibly incorporate a flow reducer from turnonesteering to take the power assist down a notch. Thx for all the info.

 

The steering gear is variable ratio. Easy to turn in the shopping center at low speeds and low assist on the highway. I assume that flow reducer would work at all times. Why would you want less power assist in a parking lot? At least try the system without that flow reducer doohickey first.

 

Yep. Good point. I will definitely hold off on the reducer until last.

 

you can modify the saginaw pump easily to reduce pressure and flow by getting a different flow control valve/spring setup.
