Please help! Sanus' SMF218-B1 sonos beam mount screw holes do not line up with screw holes on the back of the TCL 43S403. FYI the 4 mounting holes on the back of the tv are 2” from center. The smallest option on the sanus bracket are 4” from center. Neither Sanus or TCL have a solution. Anyone know of a 3rd party adaptor to make these fit?
