Final tank prep before pro-seal

I riveted a handful of things that I could do before I needed to proseal parts. All of these parts I back riveted by spacing my plate up with a piece of plywood that I had from making leading edge fixtures.

I riveted nutplates for the fuel sender. These will all be covered by the sending unit that will seal these rivets.

I also back riveted the nutplates and stiffener to the access panel. Same story here, as the cover seal will cover all of these.
