The removal of the shell went smooth with all the advice of Air Forums. Thanks to all that share the results of their labors.
After removal of the belly pan, tanks, floor and all left on the frame I found the frame rotted in the rear as expected to find, but also found all outriggers damaged to varying degrees along with 3 areas of major rot through the main frame.
This brings me to the decision of a new frame. Thinking of building heavier and looking for examples of what has been done and why. any and all direction appreciated. Just not comfortable patching plates over the number of rust holes that I have. Does any body know the size of the new AS frame members.
I have kept a photo log of my rebuild and will post pictures as soon as I figure out how to do this.
I forgot to mention, I have a 1976
