Bolts that snap when tightening usually aren't seized in the threads. Most of the time it's bolt that,s been brittled by age. The punch and hammer trick usually works. If not, then Sears sells a kit called "Bolt-Out" that are a variation of the left hand twist drills. Unless the bolt end was spotless and oil-free, then the JB Weld probably won't hold, but worth a try.
We tried to clean both but I just went out and tested it and it came right off with little no effort so it didn't bond to either surface. So much for cashing in some karma. Will look into punch next. It's just such a small surface, I have my doubts I will be able to get it to work.
