Good luck with your search...I too used a nationwide search on craig's list, also used ebay (where I found mine), auto trader, etc.
From what I've read, there were only about 2,248(?) cabs imported into North America and I wanted a cab with the manual transmission (my only regret is I didn't buy the "raspberry" cab with a tip because I wanted the manual)...so, there weren't that many out there and who knows how many are left...
Again, my suggestion is to try a nationwide search. Finally found one in Tennesee that was kept in a garage and you could see was loved - - and at the right price.
The downside is that it took about 6 years to find the one...
