Brief Description: Rivet rear seat ribs, fit baggage ribs
As suspected, it was suggested that the outboard ribs be dimpled before continuing. So, that's what I did. After dimpling, I assembled the outer ribs and then riveted them together. Then I did the rest of the seat ribs, working outboard to inboard as the directions suggested.
Once the riveting was done, I clecoed the next bulkhead on and match-drilled the #30 holes. Then I added the baggage area ribs and match-drilled them. Finally, I added the step mount weldments and match-drilled them.
