The only two minor problems I had with the fuselage floor were:
1). The rivet call out for the cross member L show AD4-4 and when they protruded they looked too short. I took out the Avery guage and they barely made the AD3 height so I replaced them with AD4-5's and they were spot on the guage and back riveted fine.
2). The intercostal ribs had to be bucked with the offset set that I used for the Z brackets. I could probably have used a staright set if I had bent the floor rib tab and then back riveted the floor rib. As I had already done that I had no choice. But they set up fine.
Careful attention has to be paid to rivet/dimple/countersink callout as many are not riveted at this stage
