Mounted the inter wing rib on the left wing by securing it at the nose sheet and the cross brace. Pop riveted the aft end to the trailing edge pipe. Remounted the left wing to the wing stubs using a 1/4 inch push pin in the main spar and an AN 4 bole in the aft spar. Cut out the area near the drag cable turnbuckles to provide clearance. Reinstalled the drag cables on the left wing.
Installed the cross brace in the aft lower inter corner of the wing.
