After the cross members and ribs were dry, I riveted the cross members to the F-802L only as teh F-802K is riveted to the cross members and the floor later.
The K1000-6 nutplates were riveted to both the F802K & L and the 5 K1000-8 nutplates were riveted to the floor.
The called out rivets for the cross members and the F-802L were back riveted to the floor.
