Looking pretty good so far, I never would have thought of trying that!  I would have to pull my drawings out, but I believe the rear of the fuselage is shaped a little differently between the early variants and the later variants.  I will look for some of my drawings and then I will lay one over the other and then post them here so you can see any differences, I hope that will help.  What did you use to build the nose up?

Thanks any help would be great. I sliced and diced the front nose and filled in and shaped with bondo. It is easy to use ,sands well , sets up quick and is cheap. It is a little smelly.
