You got it Hotrod, that's where I'm heading if the easy stuff doesn't work out.
If all else fails, HeliCoil! Be nice to keep the pan on if I have to go with a thread insert, will help keep any cast iron chips and dust out of the motor when it's drilled and tapped.
I'm really hoping the threads aren't totally gone in that hole. The bolt I took out was threadless...looks like somebody but it on a lathe and cut it smooth. I'm surprised that happened, you would think the case block is weaker then steel bolts...but it looks like the block won. Or maybe the both lost and the block threads are smooth too...we will see.
