Any listers in the SoCal area have an extra power steering box for sale? My 70 Ambassador started to leak a little more today and I need to replace it. I believe all AMC V8 cars in 1970 used the same steering box?
I'm fairly certain all PS boxes 1970 up (if not before) are Saginaws and you can get one from practically any AMC or GM car. 1970 will be flare fitting, is all, vs. O-ring. Ratios differ, there's web pages dedicated to IDing them, but likely you've got 3.5 turns lock-to-lock or slower, they don't get any slower than that and faster is nice though unlikely to find at random.
