Clamped and drilled the F-714 aft deck to the longerons. The rear fuselage was a little out of level. I clamped the boars shown in pictures to the rear, and placedthe anvil at the end of the board arm. This brought the rear into level. Fabricate and drilled the F710B, and F711C angle brackets that attach to 710, and 711 bulkheads.
