I dont think a screwdriver will work, Being that itis torqued on there so tight i stripped it with my 10mm deepwell

 

EDIT: Oops. Again im messing up names of things. I didnt mean channel locks. I meant vice grips. I always forget what some things are called. This is what im talking about

You can get then faily cheap and its exactly what you need i think. Everyone should have a pair if these i think because they definetly help in situations like these

 

Tried the vice grips.... bolt is torqued on too tight. Heading to the father n laws tommorow, he has just about any tool you can think of. If i cant get the bolt out, i will just cut it off. Theres like 15 bolts on there, i dont think missing one will hurt it any with a new gasket and rtv on it.
