Strengthen wing skin 3-4 connection - part 7 - completion

The spacers and doublers developed some months ago were finally rivetted as a part of the final topside wing skin rivetting. All holes matched perfectly. The only exception was the frontmost two rib12 flange holes which showed the expected ~0.1mm mismatch (due to this rib being dropped 0.8mm) - these were cleaned by chuck reaming. Not an issue as these holes are what the rivet tail swells into.

Perfect result - wing profile unaltered.
