Last weekend my son and I were working on my car. I have a 64 Nova. I was trying to get one of the headers out. During the process we decided, no way around it, we had to drop the starter. While trying to un bolt the starter we rounded the bolt head. My son went to work and I spent the next few hours with a dremel and a cutting wheel, chisel and grinding stone with about 3" of space to get the damn thing out. Finally got it out. Below is the pic I sent him afterward.
