I've been trying to decide where to mount the headset jacks. My centre console is the old design that placed them on its side, behind the seats. That's a safe place regarding the potential for bumping the headset plugs but less than convenient for plugging in & inflight access. I also have LEMO jacks to install so I have decided to place them all on the console in the same position as the current factory layout with the LEMO jacks between the GA sockets. That required forming holes in the console skin & producing the oval shaped holes for the LEMO sockets in the small mounting brackets. I'll produce blanking plates for the original holes in the side of the console.
