The PBY I bought and am starting for the Pearl Harbor GB (Same as this GB) is #85-5617....copyright 2008.
Cockpit tips: Step 2....pg. 3....instructions show completed seat assy's fitting to cockpit floor and rear cockpit bulkhead in no particular order. Beware!
Rear bulkhead (part 71) has a transverse brace (an arrow in the instructions points right to it) that must be trimmed flush with the bulkhead......do this 1/4" each side of the hatch....otherwise the floor will not seat properly. Then attach the floor(#39).
Do this first and THEN attach completed seat assy's. Use CA to attach the seats! They each have 3 glue points....two in the floor and one in the bulkhead.....that is still not enough for solvent glue.....they want to sag.
Drill all the way through the bulkhead glue points so you can add/apply glue from behind.
But trim those spots I mentioned......it will save you a big headache!
