Hey Don, I dont know if it will help or not, but Parts Source, has a tool "rental" . I've never used them but they may be able to help you out. If you get to the point, maybe a LH drill bit. I have used them on smaller stuff and they worked great. Or like Pettyblu said, tac a wrench on to it. Good luck, let us know how you make out and what you end up doing
