Hi Steve,
I am restoring a Ford FAT Cab 12. I have a full chassis with engine and winch, engine bonnet, front cowling and the front part of the cab. I'm missing the doors and the rear body/lockers also. Here is a link to an old ebay listing for a Chev Cab 12 FAT shell. Is this location near to you?

Let me know when you have a minute. If I find out or here of anything on this side of the pond, I'll let you know.
Regards, Richard
