Interior panels accessory progress

I attached the Aerosport pocket cover, using a ruler to keep it flush with the inboard surfaces, and then the cupholder per the instructions (but using locking nuts behind them instead):

I installed the rear vents by first taping the akward-fitting duct to the skin, then opening up the holes on the interior panels to match:

I then aligned and drilled holes for the vent levers, to ensure their aftmost position would shut the vent:

I also installed most covers on the aft section of the fuselage, since those were done anyway:
