LG C2 mounting dimensions?

[WCE_Osiris]

Hello everyone! I am struggling to find technical drawings or even simple measurements for where the mounting position is located on the back of OLED77C2PUA or OLED83C2PUA. From the images it looks as if the mounting position is manufactured on the lower half of the display as compared to my current tv where the mount is dead center. I’d like to know the measurement from the edge of the lower bezel to the bottom mounting screw holes.
 

I believe I am going to need a new mounting location to ensure that the tv is not setting too high on my wall but due to some limitations I have with the wall I wish to mount on. It may require some additional engineering due to pre-existing recessed receiver cubbyhole.

 

I have searched online and I tried contacting LG for this data via their online support and they were unable to send me the information! Which is beyond me as to why that is. Any help here would be greatly appreciated!
