Why do you need to remove it?
Anti-clockwise @tu*
The ram mount for it uses a sort of rubber expanding bolt thing so no need to remove the top nut..
And if you remove the top nut and put a bolt through the hole you will not be able to retighten the top nut up cos it will be full of bolt !
Those of us who are not dripping dosh for a pucka ram mount have used a long bit of threaded rod all the way through the top nut, right through the yoke stem, and out the bottom with a nut and penny washer underneath @tu*
