Good luck on that mate. Your chances are practically zero in the U.K and i wouldn't of thought they would be much better in the states. Your best bet would be to search the net and see what you can find in the states and import one that needs a total restoration. Finding just the shell will be difficult but you might get lucky. A search of classic american cars will bring up lots of dealers and if you don't see what your after then give them a bell. If there is one available they will find it. Personally i would give up looking in the U.K and start looking in the states, you have a far better chance of finding it there than anywhere else. Going for one that needs restoration would be cheaper in the long run than building one from scratch.
