First, I installed nutplates behind the rear bulkhead to screw the shelf to, then I prep'd, primed and reinstalled the angle support bracket below the door. When that was done, I decided to go ahead and finish rivet the door in place and cut the carpet liner. The door fits well and I'm very pleased with the overall result ... should be functional for storing hat/sunscreen/lunch etc where it can be reached with the canopy open, but without having to step onto the wing or into the cockpit. Another modification complete ... only 200 bells and whistles left to go!
