I?ve just completed this stage, now waiting for Proseal to cure. I looked many times for instruction to complete the last 6 rivets you mention but couldn?t find any. I just came to the conclusion that with all the rest of the Closeout completed and the next step inserting the foam ribs it was time to do it.
