i'd buy a new shell, just a FYI i sold my old r33 shell for 2.5k with no running gear, brakes, suspension, but the body, interior was complete, even has a basic audio system the engine bay had a respray with a Greddy fmic plus a heap of other goody's, i even when to hassle of putting in his suspension, brakes, diff, control arms so it would be rolling, as the poor buyer had his clean stock r33 stolen and torched, if you want any tips or advice feel free to ask as i have done a few r33 and know them inside out.
