I completed work on the forward baggage floor modification by dimpling the three holes in the overlapping edges of both of the floor pieces, installing the three countersunk nutplates, and setting the final three rivets on the new floor stiffeners -- the ones I couldn't reach with the hand squeezer.
I also laid out the Main and Essential fuseblocks/busses and the Schottky diode & heatsink on the back side of the avionics access door. I played with various configurations that would allow everything to fit, while still leaving room for the deep avionics on the left side of my instrument panel. I made an effort to ensure that the wires from the Essential buss will clear the top edge of the door opening once they're attached to the tabs.
