Did the rear bulkhead( previously bypassed). Organized into bins the cotter bind, safety wire, fiberglass tools, and clevis pins. Also fixed a couple of prior mistakes, including the mounting plate for the FLO-SCAN. Sharon deburred the upper firewall. Stainless is a real PITA. Ordered some small parts from Spruce and Vans. Ready to take on the fuel line bending and flaring next.
