Forgive me Dervis, I still don't understand the first part of your post above.
When you talk about steering alignment, this is set by adjustment of the track control arm going from one wheel to the other. This sets toe-in or toe-out or otherwise the relativity between each wheel.
This is wholly independent of where the steering wheel/steering box is positioned, it can even be set with the steering arm totally disconnected.
That is not the issue here and I had/have no intention to interfere with your steering alignment.
My advice is to adjust the steering arm (it's a different member) which runs from the steering box (Pitman arm) to one of the wheels. That arm (and only that arm) sets the relationship of the wheels to the steering wheel.
It means that your steering alignment guys haven't understood, or they don't know what they're talking about, or more likely can't be bothered, because adjusting the steering arm to centralize the steering wheel is so simple, technically and practically. You simply slacken the clamp bolts on the ball joints at each end and rotate the shaft, until the steering wheel is central, then you tighten them again.
I've done it on many occasions when the alignment has been adjusted asymmetrically, which itself is not correct, but generally not a problem, it just means you have to re-adjust the centralization of the steering wheel, as in your case, and the many times I've been faced with the same problem.
