I bought my last left hand bits @ Autozone $6?.  Another option is lay a nut one size smaller on top of broken bolt mig/tig inside nut, remove w/ wrench.  On smaller stuff put use a washer slightly smaller tack then weld nut to washer.  Am going to use the last method on 359 muff.   Kid that was helping me broke e-z out off in muff support bracket hole (5mm bolt) me telling him don't pull too hard you will break it.  2 breath's later I heard him cussing.

Shep,
I had this exact same problem on a 359 this weekend. When I took the bolt out, I only had the last few threads on the bolt head. I soaked it in PB and heating it with a torch, then drilling it and using an extractor. It was too deep and wouldn't budge. I finally kept drilling it with progressively larger bits until I was nearly into the threads, then I took a M5 tap and used it to cut the remaining bolt out of the threads.
