Time to drill another rivet I think. The bottom lonererons are side specific. On these the rivets are off set except where a rib joins them. See pic one. Now on the rib a where it meets the longeron at rib a the holes are off set. There is no way in the world I can rivet the rib to the longeron see pic two. Thinking just drill another hole for an extra rivet. Thoughts.
