Right tank J-stiffener riveted to skin and ribs in progress.

Right tank stiffeners riveted and ribs clecoed in place. What a bear it is to form the skin around the nose of the ribs. Much tougher (due to the thicker skin) than the outboard leading edges.
Glad that’s behind me!

Right tank ribs and J-stiffener sealed to skin.
