I trimmed back the ends of the replacement skin stiffener (replacing the one that had a crack) and clamped it in place. I then match drilled in to the skin and clip that attaches it to the firewall stiffener.
I temporarily reinstalled the rudder pedals so that I could mark the new stiffener for the holes that are used to attach the mounting blocks.
After priming the stiffener, I riveted it to the attach clip and riveted both clips to the firewall side stiffeners.
Since I mixed up an entire ounce of primer, I also shot the bottom of the forward seat pans so that I wouldn’t waste it. These will be removed from time to time, so they’ll likely get a little scratched. This should help protect them from corrosion.
