That was it. I could not see the screw slot for all the grime that was in it. Unfortunately it appears that adjustment was already tweaked to it's MAX. I tried to tighten it some more to no avail. So the play is still there with no change.

My guess is the spline or receiver gear coming from the steering column have just worn to the point there will be significant play in the steering. Dang it Mitsubishi this truck only has 183K miles on it and stuff is already wearing out on it.
