What is the aggregate wisdom out there on whether or not to put clamps on the side windows where the fuselage vertical tubes are. The port side D window has a pretty large area of geography without any support. Ditto for the upper door half on the starboard side. I've looked at the pix, and I see some cubs with clamps to help hold those windows to the tubes, and I see some cubs without. I'm leaning towards putting a single U clamp on each those vertical tubes to help keep the windows tight. What say you all?
