i have to deal with that a lot, especially on carrera lowers. i made a tool from a big fat spiral easyout. a #6. cut it off with a cutoff wheel so the taper just starts in the hole of the nut, put a 8 or 12 point socket and short extension on it, and beat it in with a big mallet. it will flare out the top of the nut if you did it right. never failed me yet. use a long breaker bar to snap it loose. this old thread has a picture of the tool. http://forums.pelicanparts.com/showthread.php?threadid=69827&highlight=spiral+easyout
