Finished riveting what I could based on the Homebuilder.com video. Left the HT mounting brackets, the rudder cable fairings, the upper longerons, forward 2 'L' brackets on both sides and all of the top of HT channel unriveted but left clecoed in place.
Cut gear channel to size. Used cabin floor (6B10-1) to help mark (27mm) off each side. Marked, drilled and clecoed in place. Removed. Then clamped, marked drilled and clecoed Rear Seat Panel (6B5-1) in place. Removed it and then reassembled with gear channel and seat panel to check fit.
