I finished off the rivets on the cockpit side rails and clecoed the bulkhead caps in place. The bulkhead caps will get riveted on much later when the forward upper skin is in place. Then it was on to the seatback supports. I clecoed both on and riveted the bottom 4 rivets - the ones I could reach with the squeezer - as the rest will have to wait for a second pair of hands or some ingenuity as I cannot contort both hands in there for bucking and driving.
