Finished installation of angle to support the rear of the Avidyne Nav tray. Match drilled, deburred and primed angle prior to riveting to the subpanel. The angle attaches to the tray with #6 screws. Made some spacers to ensure an even gap around tray and subpanel. Also spent some time inventorying the cables and connectors from Advanced Flight to determine what wires I need to complete the avionics installation.
