95% can be single person, the rest is scattered around at widely separate times.
For the tail cone, backrivet. It's fairly easy to hold a significant flat bucking bar against the skin, and reach over the top edge with an extended (12") back rivet set. Near the center, lay the assembly atop your table-top back rivet plate. Two people make it easier, but beware that it's a springy assembly and not readily clamped so getting proud heads is more likely than when rested on a table and back riveted.
Center section is mostly one person.
Forward lower often requires two when reaching towards the floor over the top edge.
