Left Handed Nuts!

[JIMRPT@AOL.COM]

EtAl;
 I am in need of some left handed or 'reverse threaded' nuts...specifically 
in size 1/2" X 20. After searching all my catalogs and the World Wide Wait I 
have found plenty of sites that are ....shall we say 'different' :-) such as 
"lefties and descent into darkness" ???? And places where I can special order 
several thousands of "custom" nuts...the hardware type :-), but none where I 
can find/buy just a dozen or so..............any sources or ideas out 
there.....about the "hardware" type nuts-???
