Riveted baggage floors to the mid fuse assembly using AN470 AD4-9 and 10 rivets. Did reasonably good job avoiding any scratches to the floors. Difficult to secure the L/R outboard rivets given how close they are to the corners.
Clecoed the ribs to the assembly and realized that I over dimpled some of the holes where nutplates are to be installed. Removed the ribs and managed to flatten the holes should not have been dimpled yesterday. Reassembled and all seems to fit together flush now. Will do all the riveting tomorrow. Pulled parts from the various storage areas in my garage for the next couple of steps.
