Nosewheel Steering Adjustment

Hi All, Again,
I managed to get access to the bottom of my yoke without removing the floorboard. What I found for the nosewheel steering was the pushrod with the usual ball and socket link. Nothing there to adjust. So, logically, and judging by the service manual, the adjustment must be at the nosewheel end of the pushrod or something in that location. But darned if I can easily discern how to do it. I need something more detailed than what I've found so far, which is along the lines of 'adjust the alignment at the nosewheel strut'. Or, am I not seeing what I need to see at the yoke end? So, if anyone has detailed directions how to accomplish that adjustment, I'd be most grateful.
P.S. I know the end cap of the pushrod is threaded and can be adjusted in and out. Is there a threaded plug inside the rod that can be adjusted?

Thank you
