Still cleaning up little tasks until I get a helper to mate the center section to the fuselage. Since the belly skin is now riveted on the center section, I don't really see any reason to delay installing the crotch strap brackets.

I clecoed them back into position, then installed the floor pans with enough screws to make sure they were in their permanent position, then match drilled for the 4 nut plates that go through the seat pans into the flanges on the top of the brackets.

Pulled everything back apart and painted the part that will show through the floor rattle can Rustoleum flat black. Once had dried, I installed the nutplates. Was at a good stopping point, so I called it a night after bringing them into the house near a heat register so that the paint would have a chance to get good and hard over night.

This morning, I installed them with LP-4 pop rivets per print.
