I dimpled bottom flanges of all seat and baggage ribs, as well as the F704B bottom flange. To dimple the F704B center bulkhead bottom flange, I had to remove the support bracket for control column. While the control column brackets were off, I realized that I need the bracket out of the way when setting the rivet underneath them, so I just put the brackets away. will install the brackets when I am done with riveting bottom skins.

Van's instructed to install the nutplates on the ribs at earlier time, I delayed that installation to now, after I primed all ribs.

I decided to use the Van's stock crotch strap, so the gap between the crotch strap brackets is 0.125". I then drilled all crotch strap brackets to ribs and seat floor panel. The fit is good.
