Question on '70 column, lower bushing?

Hi,
I looked through older posts for this and I found a lot of posts using a sleeve bearing on a manual steering column however, I couldn't find any with the auto shift column sleeve.

I want to keep this car as a column shift if possible so my question is, do the '70's have a bushing in them to center the shaft in the shift sleeve or does it free float with only the top bearing centering it?

I can see them being free float with the original coupler and PS box as the distance between the worm shaft and steering shaft end is short however, since I'm converting to manual with a FR adapter shaft with a universal joint, I can see where the shaft will be able to flop around within the sleeve as it turns because of the additional distance and force needed with the manual box.

I was thinking of turning up a delrin bushing and cutting 2 snap ring grooves on the shaft to retain it but wasn't sure if that would cause sufficient drag on the shift tube that would affect the ability of the shift detent to keep the car in the shift selection while driving. Obviously I would size the bushing to fit both the shift tube and shaft loose enough to hopefully not induce this issue. (I have run into just this issue on first gen Cummins pickups where the bottom bearing does not turn freely and when you steer the truck left going down the road, it changes gear selections from D to N)
