He was referring to the power steering gear box, I should add that he also services current daily drivers so he has a lot of exposure to different problems. I think what his point was if it doesn't pull to one side when you are off of dead center it proved that the problem is the gear box, I know driving it this way is not the correct fix it must be replaced but like you said I wonder what the prior owner did and where this box came from A lot of things could have happened in the past 66 years.
