I'm Awesome
Update, today the first day of 2023 I celebrated the new year by finaly adjusting the steering box as per the video above (well as best as I could with it still in the truck). I could turn the large input adjuster about a quarter turn. And when I was all done the small Allen head adjuster ended up quite a bit higher than before. The steering is now presumably pretty much as the General intended. No tight spots, with good smooth power assist, returns to straight as it should and I can drive it one handed if I want. There is a little bit of rag joint sponginess, I don't think it is totally shot but it is going to be replaced anyways.
One thing that I noticed is that the Steering box does not look like the GMT box that I was expecting it to be.. they apparently have "83" cast on the housing. This one does not. It also only has 2,75 turns from lock to lock. I tested that when the draglink was disconnected to make sure nothing else was limiting.

The power steering does struggle a little bit with going to full lock when absolutely stationary, but works fine when rolling ever so slowly. Not a problem really but this and the 2,75 turns from lock to lock makes me a little suspicious. Is this a factory 1990 Z71 steering box? (the bore seems to be 3" as the lid measures like 78-79mm)
Does anyone spot the sparkplug
