Removed lower and upper baggage bulkheads to rivet canopy cabin channel in place, then reinstalled bulkheads. Drilled correct holes for bolts for center flap rod retaining block, torqued bolts. Spray-painted a number of sheet panels, including center panel in baggage compartment (Gray enamel, I had painted the wrong side before), and seat panels and flap motor panels unexposed sides with yellow zinc chromate. Bolted flap motor to its front channel, previously prepared. Vacuumed thoroughly all floor areas in preparation for closing.
Next time I hope to at least locate where the Ray Allen flap indicator will be located.
