I continued on the area by trimming the upper baggage bulkhead and drilling holes for screws as called out in the print. I then positioned the bulkheads onto the F-706 bulkhead and drilled for nutplates. I inststalled the nutplates as described. I then modified the corrigated bulkheads to accept the seat cablle wear blocks. I reinstalled the bulkheads with all the screws and fitted all the baggage area internal skins and screwed them down as well. I then fitted the center tunnel cover an screwed that down as well. The last step was to fit and match drrill the F-6111 ribs onto the top skins.
