Baggage floors and firewall

Nothing very exciting, but a long 3+ hour job of fixing the gasket issue on cylinder #4 (it was upside down!) and drilling out a few rivets connecting the subpanel to the fusealage/firewall and the floorboards. Why does it take so long? Well, to get to the floorboards it's pretty tight - I had to lay down in the tailcone basically. On top of that, I saved all the "hard" rivets for today. They are in tight corners where a normal drill would not fit - thankfully the angle drill saved me.
