Here is the back side of the panel prior to installing in the plane. One thing I forgot to get a picture of was the installation of the Radio stack brackets and the EFIS mounting tray. The radio stack has two L-brackets on either side secured with -3 rivets. The EFIS tray is also secured with -3 rivets. I need to paint the heads of the rivets when I pick up the touch up paint from the paint shop.
