That was excellent Andy...I had a good laugh...my wife's not home but she's got this one particular pole at the local mall that was built just for that purpose and she could tell you where it is...come to think of it, it may not work for everybody but I do know it's worked for her twice.
Yep your right. That is what it is.A set I had one time had a wire clip that clipped into two holes in the square trim housing. You unclipped it and the joystick barrel slid out and fits through the hole in the door. Knowing GM, they likely changed things over the years to keep ya guessing.
