Measured, remeasured and marked the lower center subpanel for a cutout. The Avidyne GPS tray extends forward past the center subpanel, a cutout had to be made to allow room for the tray to pass through the subpanel. Spent a lot of time ensuring I got the location correct. Gave myself about 1/8” gap around the tray and will attach the tray to the subpanel with an angle later.
Removed the comm and autopilot panels to make the process easier, but not before taking a couple photos to make sure they get reinstalled correctly.
