With the comm radio now in the glovebox there are still numerous components that have to be installed. Using cardboard I mocked up a design that will use a hinged panel to fit under the SIC panel and extend back to the sub panel. Then I went to a friend's hangar and had a piece of aluminum sheared to fit. Next I will have to mount the new SIC lower panel to ensure there is adequate clearance for the avionics that will populate the shelf. I'll save that for tomorrow-maybe.
