Tackform mount from Dave. 100%! I just wrote a review and posted

BTW on RT you can get a really nice curved mounting bar (i think from lamonster.com?) for $50 that bolts to the two bolts on the upper dash, to mount RAM ball stuff to. This was one of the first things I got, GPS, phone, dash cam all there. Comes with couple 1" RAM balls that screw in it. Then you get the clamps on Amazon in the length you need (usually 4" works for me).
