Due to my slection of the Grand Rapids Dual Sport 8.4" screens and EIS, and use of the Composit Design Standard Electrical Control Panel, I had to fabricate a new panel and subpanel to get the clearenesses I needed without modifying the main structure (F-7107-L & R) behind the panel.
I increased the overall hieght of the panel 1 3/4" while decreasing the hieght of the main panel by 2 1/2". The new subpanel is 2 3/4" with the flanges in a Z pattern and same raduis flanges as the original panel. The subpanel fits to the main panel exactly as, and replaces the, F-746 Aft Engine control bracket.
I also used the holes in the skin for the vent brackets F-783-L & R to support the new subpanel. I modified the mapbox to 1 3/4" depth to fit in the subpanel, as well as incoorperated the vents.
