How a $1.50 part can cost $2000

1. Clean off the broken bolt as well as possible. Grind a couple of flat spots on the bolt as close to 180º apart as possible. Clean again, soak with Kroil. Let sit for about 1 hr then use open end wrench using ground off spots for grip.

2. Drill into the bolt length-wise using progressively larger drill bits. Try to go in at least 3/4 inch. Take your time so that one does not get broken off in the bolt. Use an Ease-Out to remove bolt. I prefer using a LH drill bit. When the bit bottoms out in the hole, the remainder of the bolt crawls up the bit.

3. If you have access to a welder, weld a nut onto the end of the bolt. Remove bolt with socket wrench.

Hope one of these works for you.
