California is as Muggz said a good place to start but the whole of the southwest part of US often have some good old yank tanks avail in good nick. My mate imported this baby from Dallas Texas late last year (changed wheels since then) and had no trouble at with it, still LHD and got it over the pits and licenced with ease apparently. 455 cubic inch Yank Tank cruiser and it sounds mint. He spent $26K on the purchase plus freight, duty, etc and took 16 weeks from time he saw the car and bought it to delivery in Perth.
