Completed design and fabrication of the bracket to mount the G5 on top of the glare shield. Used a fly cutter in the drill press to drill the 3.125 inch hole, and bent the sheet metal using wood 2 x 4 with clamps and vice.
Glued the "leather" glare shield cover end to the bottom of the glare shield using contact cement, and trimmed it with an exacto knife. Before gluing the "leather", trimmed the rubber molding along the edge of the glare shield in the location of the G5 mount to thin it so the mounting bracket sits properly.
