The guys from whom I ordered my panel came to help install the panel and test the avionics.

First order of business was to install the back panel support and make a vertical rack bar to strengthen the avionics rack. While that was going on we had a discussion of the air system and its effectiveness with air handling, especially to the rear seats through the side channels

I made a decision to rework the air system so some panel mods were made by first removing the airflow levers from the panel.
