RE: Wing and Stab alignment problems!
Wow. 3/8ths is a chunk!! Sounds like a vehicle alignment gone horribly wrong. Nonetheless, with the wing and tail now equally crooked, you'll probably need to dial in some rudder trim, and possibly tweak the thrust angle of the engine to get everything except the fuselage tracking in a somewhat straight line.
One thing for sure...the first guy that stops to admire the model? Make him the deal of a lifetime on a low-time warbird.
Don't chop it up though.
