I'm in the middle of a teardown as well but holding out on finding a CP upper (either the metal or plastic one) with original arts, I am sort of weird in that I would rather have beat up (to a certain extent) original stuff than perfect repros. Kinda like the cab to look straight off a game center floor with the imperfections that entails externally but internally have perfect controls, wiring, monitor etc (and no game center filth). Right now I have a river service stainless panel surround (not the full upper), so no art needed. My cab has no art at all on the sides though, so I basically either get repros or have blank sides and the cab looks strange totally blank.
