With the primer dry, I riveted the nutplates onto the floor and seat supports. I riveted the floor and seat supports to the rear centre section as well as the vertical bulkheads. The outer two rows of rivets on the vertical bulkheads I hand squeezed, with the remaining rivets for all parts being riveted using the rivet gun. I also riveted the 804 centre section vertical bars to the rear centre section using two 1/4 bolts to make sure they staying aligned while I riveted them.
