Bergman steering unit!

What`s wrong with the manual box? wore out?
If still tight, I may be interested.
I wanted power steering is why I am changing. My wife wants to be able to drive the car too and she is rather small at 5''4" and 120 lbs. It doesn't seem to have much slop in it for something nearly 50 years old. As I still haven't decided on exhaust I figured I would go with this modern unit. I can't say enough good about Peter Bergman he really knows his stuff. Along with the steering box I got the new pump and all the correct lines. He also has me a flaming river column and tuff wheel coming soon.
