Cut, debur, and cleco stiffiners into place on both tanks. Cleco skins to main spar to verify fit with top skin and leading edge. Final alignments for tank ribs. Cleco ribs to baffel on main spar for match dril. I had to remove the leading edge on each wing to get the most outbound rib clecoed and drilled into place.
Stiffiners clecoed into place on bottom side of tank skins
