Easy to tell how it was fixed. Pull the key out and turn the steering wheel til it locks. It would lock in the straight ahead position if it were on correctly.

There is a center locating arrangment on the box. One pulls the screw plug and screws in a pointed screw that fixes the box in its center position. By mounting the box in its centered position with the steering wheel locked all the rest of straight ahead is done with alignment.

There is only one right position of the pitman arm and there are markings to designate that position.
