I ended up using a long breaker bar with a 1/2" drive attached to a 17mm socket. I used PB blaster on the bolt allowing me to turn the bolt, it has backed out about 1/2 to 3/4 of an inch. When I try to use a regular 3/8" drive socket tool (approximately 11 inches long), I can't get it the bolt to budge!

I stayed with it last night until 1:00 AM cranking using the long breaker bar. I'm going back to work today again. The idea of removing the alternator bracket from the engine may be where I ultimately go with this little problem......
