Pickup an ez-out kit from your local hardware supply if you don't
already have one. Drill out the center of the broken bolt and use
ez-out to remove broken bolt. It seems to work everytime.
An ez-out, is like a backwards tappered drill bit as you screw it into
the hole you drill it tightens down and allows you to remove the broken
If all suggestions fail drill out a install a heily coil (sp?) usally as
strong or stronger then original.
It's a good idea to use some anti-seize when re-assembling. This will
help prevent bolts from breaking off. A must whenever two dissimlar
types of metal. (example: aluminum block and stainless bolts).
