Part 1 of tonight's work: I installed the Approach Stack avionics hub to the forward avionics bulkhead using nutplates and #8 screws. (Actually, the backplate is the only part that was permanently mounted. The hub itself will be attached later, after a lot more of the messy work is accomplished.) To the left of the hub, you can also see the 1/4" mounting holes I drilled for the two alternator controllers. These will get nutplates, too.
