One of the tasks that needs to be completed before finishing the panel is finishing the sub-panel. I took the subpanel out and finished the movement of the ribs inward five inches. This allows ten inch displays to be mounted in the correct visual location on the instrument panel. Right now I am planning on installing 7" displays for Skyview. But at a future date I might want to upgrade to 10". This modification still allows plenty of room in the center portion for avionics.
