'65 C-10 factory auto column questions

[nxtruck]

Guys,
I'm in the middle of changing the turnsignal switch in my son's '65 and have a few questions. 1st of all, before I started, the strg. wheel had a little up and down play in it, coming from the column. It will move up and down probably a half to 3/4 of an inch or so. I thought that there was probably a bearing near the wheel that was bad. Well, the only bearing I see is the one in the t.s. switch, and it didn't appear to be bad. With the wheel off, I can wiggle the strg. shaft up and down and see no way of tightening this up. What am I missing here? Is there supposed to be another bearing somewhere near the strg. wheel?
2nd, has anyone used any of the aftermarket t.s. switches and not had good luck with them fitting correctly? It appears that, in oder to be able to use this switch that I have, I'm going to have to drill a couple new holes inside the shroud-part of the column that the switch sits inside of. I compared the original switch to the new switch and they definitely are different in the location of the mounting holes. Has anyone seen this with these new switches before?
Thanks in advance!

OK, upon further investigation, I think I see the issue with the wheel movement. The inner column tube is solid, but the shroud that the turnsignal switch screws to is loose when it's twisted in place on the tube. If this shroud were solid when in place, there'd be no up and down play in the steering shaft. I'm not sure if there's something missing in this column or what the deal is. If anyone has any ideas, I'd sure appreciate hearing them.
Thanks in advance!

I have the same problem, but have not opened it up yet to figure out the problem. Let me know if you find a solution. Thanks.

I had that prob and what I did was find a plastic bushing. It kept the shaft centered to the tube. O.d. was 1"x 3/4" i.d. That should help.

@nxtruck, sent you a pm. I fixed my og switch (before you start that drill)

Thanks Jerry
I responded. Thanks again!!

Rob, when I get this figured out, I'll report back.

Well, props to Jerry for the heads-up on the bushing!! What I did to fix this was to find a bushing like Jerry described in his post. The one I found has a 1" o.d. and a 3/4" i.d. I sanded the inside to clearance it a little and it works like a charm.
Now, the next issue I've discovered. The factory auto shifter doesn't shift as smoothly as it should. It's kinda notchy feeling going into P from N or R and the shift indicator goes well past the D when actually in drive. I don't know if there are adjustments that can be made to the linkage or how to fix this. Anyone have any ideas on this?
