EZ Outs might be the answer.

There is a tool called an Easy Out which may help you.

Any auto parts store or a Sears store would have them.

They come with drill bits and a tool you insert into the small hole you drill and then you turn it to the left and with a little luck you just might find the rest of the broken bolt will come out without using an heat on it first.

Give it try. Jimbo

What I would try first is to weld a 5/16 nut to the remaining piece. I have much more success welding to the bolt than drilling them out with a hand drill.

You know, if that bolt isn't bottomed out in the hole, you might be able to use two sharp picks and turn it out, I've done it before.

If there's enough left just slot the top with a dremel and use a screw driver to back it out.

The 781's can be decent heads with enough work (ie time and or money).
