Today, I cleaned up the cutouts on the cabin floor center section, installed rivnuts, and then installed it. In the process, I had to remove the flap handle mechanism, and the pilot/copilot radio/mic jacks. It took quite a while to get everything back in place and realigned. Next, I worked to install the fairing on top of the flap horn on the cabin roof. I used some windshield sealer under the flange and then riveted it in place.
