Continued with the instrument panel installation. Trimmed the avionics support angles at the top end to clear the rivets at the aft edge of the glare shield. No real need for these avionics support angles to go all the way to the top. Established the hole pattern around the perimeter of the two panel faces, center punched and pilot drilled these. Held them up to the panel structure and drilled through. Made some upper support angles for the avionics support angles. These will rivet to the glare shield but bolt to the avionics support angles so the entire panel structure is just bolted and screwed in place. They will also provide a point to attach some diagonals to provide support at the forward end of the com and xpdr racks.
