Help!!!

So i finally got my lowering springs and i figured id just put them in myself. The front worked out well, but im having tons of trouble with the back. On my car the lower part of the strut connects to the lower control arm with a 14mm bolt with a 19mm nut on the other end. I took of the nut, but i broke the 14mm bolt on both sides of my car. So now i have this bolt stuck in there... theres about an inch of bolt to grab onto, but i cant find a good pair of channel locks to try and get it off. I also tried heating the bolt with a blowtorch because i read that might loosen it up, but i quit because it wasnt working so well and i dont want to melt the bushings. If anyone has any advice, id greatly appreciate it.

your gonna have to get to a shop with some nice drill bits to drill it out of there.
