    that's bad luck
    Fortunately there's a good part of the bolt left to get a grip on.

    I have had good results with a welding device, just put a small weld on top of the broken bolt to get heat in there if you have a welding device, otherwise apply heat with a torch.
    The trick : while the bolt is still hot use a wire cutter with the beaks perpendicular to the thread on the bolt, the design with sharp beak and big lever action usually does the trick for me where normal pliers don't get enough grip.

      Hmm would have never thought of wire cutters. Also haven't seen the type you posted before.
      I don't have any welding equipment but can pick up a torch. Just get the area nice and hot and grab the bolt with the cutters and hopefully should pop out? I'll give that a go. Thanks!

        welcome.

        also don't grip the bolt and just increase force trying to turn it loose,
        but apply force loosening-fastening left-right which will hopefully wiggle dirt/rust free
        between bolt and housing.
        Good luck

          Another method is to weld a nut to the piece of the bolt that's left. Put a wrench on it and go back and forth until it pops loose. I've had luck with heat and vise grips too, if there's enough of the bolt to grab. Only danger there is you might just break off the nub that's left and then you won't have any meat to weld a nut to if you need to...

          Good luck

            that's a good method.

            LOL in this case it might not be a bad thing if the rest of the nub came off.
            If the torch and wirecutter do not produce the desired result, carefully removing a few mm of the top of the remainder of the bolt may be a good option.
            it would probably leave enough of the extractor exposed to get it out and maybe even remove the rest of the damaged bolt in doing so.
