Steering gear break in period?

Chrysler power steering boxes Have a valve pivot lever that has to be centered.This is where the pressure hose connects to the top of the box.Also known as the valve body assembly. You have to loosen the bolts and slide the valve body till the valve is centered.The valve slides front to back. I don't remember if front is left or rearward.
You have to just move it(small amounts) to see if it steers on its own left or right. Move it until you get it centered
If I was there it could be done in less than 5 minutes.
Who ever did your work knows nothing about Chrysler product and gave you a real shaft job.
You can find a on line service manual that details all of this.
It may even be on You Tube.

So, I've been reviewing the service manual and searching steering boxes online and I've noticed what's in there now isn't the same unit as what was in before or what's in the service manual, so it won't help me adjust it. Photos inserted below. I am not sure what style it is or where to look to adjust it. Looking through Yearone, it looks a lot like this one.

The real puzzling thing is that this is a pretty big shop that always has a bunch of classic cars in it, including obscure things like a Nash Metropolitan and early 1920s roadsters. There was even a Duster undergoing a 6.2 hemi transplant plus a full power disc brake swap in the bay next to my barracuda so the idea that this simple install could be so badly botched is especially hard to swallow.
