Finishing Bottom Of Fuselage

I'm starting the last of the bottom of the fuselage before the the instructions say to "roll the canoe". You have to read the blueprints to determine what is left to finish. I'll need help with the riveting as my arms aren't long enough to reach inside and outside at the same time.

This picture is looking in through the firewall recess that's removed for access.

The fuselage is still upside down. I'm hoping Austin can help with some of the harder to reach rivets and we can flip this baby by Christmas.
