The battery terminal bolt on the positive side battery for my 96 blazer is completely stripped. The only way i can loosen or tighten this thing is with vice grips. Any idea how i can replace this piece with a new bolt and where i can get it?

 

Any decent autoparts store should have a replacement available for cheap. Some may only carry the add-on lugs, but they are still cheap. The add-on lugs offer a much larger hex head to them so stripping them in the future will be difficult.
