I took several days and riveted together the center section. It took two days and about 150$ worth of hardware to install nutplates on all the ribs for the seat and baggage ribs. I feel this will be worth the investment later when I need to run wires or get to antennas and such.
Riveted the spar and ribs together.
Installed seatbelt anchors.
With a friend's help we banged out the skin rivets.
