I back riveted the firewall angles to the firewall panels. Lots of AN426AD4 flush rivets. I'm finding it rather cumbersome moving the back riveting plate around to avoid dinging the flute that runs diagonally across the stainless sheets.

Here's the left and right firewall panels with the bracing riveted on. Tomorrow I'll begin riveting the top panel and angles.
