I got it at a place here caleld Gregs Distributors.... It took a LOT of looking around for it here, and I live in a big canadian city... check around to a few auto body supply shops... thats what everyoen told me to do
EDIT: Just checked where you were.... I thought you may be closer, but it cost me $30CAN for a kit, ended up using the 'RIV NUTS' from the kit instead, worked perfectly.
I was calling it a threadsetter, but no one knew what it was... I was told other names for this tool are : RIV NUT SETTER, or... crap cant remember the other name, lol...
Hope this kinda helps....
