Today I fit the aft top skins. It took alot of straightening on the bulkheads. When fluting them several weeks ago, I didn't think about the angle that the flanges need to be so they were closer to 90's than what they really needed to be. Anyway, I got them fitted along with the J stringers. I drilled and deburred all of it. Then I added the bulkhead gussets and riveted them in place.
