Did he disconnect the intermediate steering shaft from the box, or the pitman arm from the box? It sounds like he got one of these off-center, and tried to correct it by merely adjusting the sleeves on the tie rods. Otherwise, you shouldn't have any significant change in turn radius, the tie rod ends should have plenty of thread to use the Hotchkis adjusters, and they should be pretty even in terms of threads exposed across the board. At this point, I wouldn't be trying to discuss it with him, I would be trying to find another alignment guy. If he even gave you your car back with the steering wheel 90 degrees off in the first place I would have to question his basic understanding of what he does and how he does it.
