After having determined a good mounting location for the avionics hub yesterday, I figured out where to mount the two alternator controller boxes -- on the same bulkhead as the hub. Once again, this required the temporary installation of a brake line. I'll use 1/4" pan-head screws to mount the controllers, with the head on the front side, inside the baggage compartment.

I also worked on the lower-right map pocket and the bottom-edge stiffener I designed that will be riveted to the inside of it. (The stiffener will be on the bottom inside of the pocket and will prevent the passenger's foot from bending it.)

Finally, I match-drilled the pocket mounting holes in the fuselage and deburred them.
