Having got the whole WD-409 saga behind me, I carried on with the rest of the bulkheads. They still need to be edge-finished, but after that they will be ready for priming. The pictures below show all the parts that go to make up the tailcone.
Shown on the left are the upper bulkheads supplied as part of the Tom Clark fastback kit, and on the right are the ones from the Vans kit that are being replaced. I already cleco'd the forward F-807 upper bulkhead to the fuselage, but I later found out I don't even need these bits yet.
