Hmmmm, this may not help. But when I last insalled one, it was an Auto Zone switch and the post just slid into the switch and locked with very little force to almost none. If I remember right, the post had four sides or was square and so was the switch receiver part, so it all lined up without setting anything.<br><br>Maybe try taking the switch out and fitting the knob arm into it without the dash in the way first, just to see how it fits and sets. Then you should be able to release it with the button on the switch and repeat the process untill you are an expert.<br><br>One more thing. I had to shim my switch back away from the dash with a nut between the switch and dash to get the right fit for the arm lenght.<br><br>Good Luck !
