The next task is to figure out how much the left window needs to curve to mimic the right side cargo door. Since there is no structure on the left side, I put a couple of levels on the right to simulate the angle of the aluminum skin line and fabric transition. Once the fuselage was level, I checked the right level and saw it was 83.5 degrees. I took another level to the left side and place it in the same spot on the frame as the right side. With clamps I slowly pulled in on the top of the frame until I had 83.5 degrees. I kept those angles and welded in two top attach points to lock in the angle. It should look pretty even from the back.
