Be very careful with the ezout.
It will only work if the bolt is free to turn. If it is bottomed out, rusted, or seized, no the ezout will not work and if broken off in the bolt, the problem is made worse!
If you can score a left handed drill bit, all the better. It just "mite" grab the bolt and spin it out.
Otherwise, make every effort to drill EXACTLY in the middle, and as straight as possible. If it doesn't move, the end result will be to drill the body of the bolt away and surgically tap the remaining threads out.
That is why it is so important to keep it in the center and straight.
