POWER STEERING

Hello,
I use my AA as a daily driver and would like to add power steering, especially when in town parking in tight spots. I'm looking for a steering box that will fit reasonably well in the STD location. I have done a search of the forum, but could not find anything.
Any information or input would be appreciated.
Chris

Find a '73 Chevy power steering unit. These have a valve operated by the steering arm which activates the steering ram. You need to make a bracket for the pump and line it up with the water pump/fanbelt. You need to modify the linkage between the steering arm and the front spindle. Bolt the ram to the rod connecting the front wheels.

Interesting Ron,
Have you done this conversion or seen it being made? Do you have some pictures? I guess the steering box have to be turned 90 deg. so the pitman shaft will point sideways.
You suggest a '73 Chevy PS unit, but are they not about the same way up into the 90's?

The Restorer had an article on power steering. "Power steering for Model A," photo, Jan-Feb 1963 (7-5) p 3
Ford had a system similar to what 1wonton described in the 50's and 60's.

Wow, what a fabulous response from all of you 
My AA is fully restored and the steering box and all suspension and steering components are rebuilt. When I jack it up, I can turn (not rotate)(yes that too) the front wheels easily and the steering wheel spins. It's definitely lubricated, so there are no problems with the truck being old and stuck.
I have desided to install a F100 steering box. The worm and roller type will give less friction and 18:1 ratio over 15:1(I hope those numbers are correct) will probably be enough to make me happy. If not, I will instal an electric PS under the dash later.
Again, thank you all!
