While searching for info on the internet about fuel line firewall penetrations, I stumbled across a builders log that described adding nutplates along the bottom flange of each of the front deck ribs. This would allow him to add adel clamps to secure wiring later in his build. He also drilled some wiring holes through each rib as well.
I thought "what a good idea", so did the same.
