Attached the center fuselage to the aft section. Picture #2 shows where I need to trim a baggage rib to fit around the rudder cable guide. Cleco the 770 forward side skins to the fuselage. Fit and drilled the 720 armrests to the fuselage. Removed the 770 skins and made the conical bends 90 degrees at the lower end of the skins.
