I've screwed one of the balls onto the dash. Built a backing plate out of 1.2mm gal sheet I think it is. The arm goes from the ball on the dash to a ball attached to the backing plate. The Ram mount screws to the backing plate and into the pen holder part of the dash as you can see.
It is VERY rigid, corrugations.vibrations barely bother it.
