yeah it sucks when that happens, though normally its not the helper its the bolt, sometimes ive tried to get off and realise its f'ed then get out the hand ratchet to easy it off and it still snaps.there is no real easy way to get them out, some its just a pair of vice grips, others need a drill and they all suck. Good luck, it could be worse the could be in the gearbox XD
