Installed sub-panel back into aircraft, the left side is riveted together but not to the airplane. The right side needs riveting. I am going to place two angle brackets (angle aluminum) across the bottom of the sub-panel for hanging Adel clamps for wiring. After that I will be ready to rivet it into the aircraft.
I put the instrument panel in to check alignment and fit after riveting the sub-panel. Everything fits fine.
