After watching the video here I knew this was the only way to go. Worked great and the mirror is mounted solid as can be. You have to crank pretty hard on the little wrench to collapse it, at first I thought it wasn't gonna work. Also, I used a flat wrench as the stationary wrench because a normal wrench made it difficult to get a good grip on the nut.
I was tempted to take a star away because the nut you crank on was a bit undersize but it worked none the less.
