Well it looks like I'll be yanking the column back out and tearing it down. Found a ton of slop, about .25" up and down, not in the steering shaft bearing which was a good tight fit to the shift tube. All the looseness was in the fit of the white nylon bushing of the shift tube to the outer column tube. So I'm going to see if I can eliminate the shift tube/nylon bushing and the bearing/spring/retainer stuff off the steering shaft to fit a collar bearing in there to tighten things up.
