Made the plywood backboards as shown on DWG85 to provide a work platform to lay on while working inside the tailcone.
Cleco'd the aft top skin to the fuselage and riveted it in place.
Riveted the F-858-1 shoulder harness anchors to the aft top skin.
We ran out of AN426AD3-6 and AN426AD4-5 rivets, but fortunately we had ordered extra -7 rivets from Van's previously so we just cut them to length with the rivet cutter.
