Ok, so I made some progress with the slop on my granite and for pretty much free.
First, make sure your steering post fins are tightly screwed to the flat bar peice with the ball studs on it. Use a drop of CA on the threads to keep them from loosening up which otherwise happens on mine every 10 packs or so.
Then I made a new pin for the side without the servo saver that clamps the fin like the servo saver side does. This eliminates the slop between the pin and the fin. I cut the head off a bolt of the proper length that had a thread OD of 3mm. I ground the threads down at the top and bottom to 2mm OD so they engaged the holes properly. I used a flat nut on the bottom that was ground down to fit the bottom of the fin and, once in position on the pin, crushed slightly in a vise to make sure it stayed put. At this point it is basically identical to the servo saver side pin but with threads all the way down. Then I threaded a locknut on the top, upside down, and tightened it all the way down to firmly clamp the fin.
I also jammed some small shims, little peices of a zip tie, into the holes on the underside of the servo cover until all the up and down play in the pins was gone.
These three mods took away at least 75% of my slop. Not perfect by any means, but definitely close enough to make me happy.
Here is a pic of the pin, the nut shown by it is not the locknut style I ended up using.

I'm very interested in doing this to my granite. Tower has not had the mounting post for a while now and my granite is collecting dust.
Do you have pics of what locknut style you did use?
Thanks in advance.
