Fluted and filed the aft, F-810A bulkhead to try to get it to fit. (I plan to either make a new bulkhead, or send this one back to Vans and get a replacement part. As I mentioned back in December, this bulkhead is grossly undersized on the sides. There's at least a 1/4" gap between the bulkhead and skin on each side.)
Fabricated F-805C and F-805F floor support pieces.
Installed a #8 platenut in each of the already-existing F-805D tabs.
Taped the F-805F shims in place on top of the F-805Bs.
