Dismantled the empennage from the fuselage, deburred all the drilled mounting holes, corrosion proofed the angle and attach plate for the vertical stabiliser. Rivet these parts on. I also finished drilling and prepping in the two pieces which are riveted to the curve of the top skin forward of the baggage tunnel. There is not much information in the way of explaining where or how these go two curved pieces go. Sort of check the diagrams and away you go.
