broken raptor...can't get the steering stem off
 

Hey guys,
I'm new to this forum and looking for some help. I dropped my raptor 660 off a 20 foot drop upside down...With me on it. Fortunately I'm fine but in the process I bent the steering stem and frame portion that supports the upper portion of the steering stem. My issue is that I cannot get the 22mm self locking nut off the bottom to remove the stem. Anyone know any tricks to this and maybe a trick to bending tube steel back with out crimping it (about 1/4 inch)?????
