Today, I worked to complete the gussets etc. on the rear bench seat, including the cutouts for the center seat belts. I primed everything before final riveting. Then when I installed it in the aircraft, the rear upper tube didn't come close to where the plans have the attach brackets. I'll need to drill them out and move them up one inch and then move the atach point closer to the forward edge of the baggage door. The only other option would be to try and induce a greater bend in the tubular frame, but that would be a bit more risky. I believe that however is the issue, if the frame had more of an angle, it would fit per the plans. I'll sleep on it.
