hello..im having trouble seperating my wishbones and axle. these damn perches have a nut that wore away and i can't get to them. i tried cutting off the stud thinking it would just bang out, but there's still a little bit of that nut holding things together. on the other side there's more of the nut, but still no go. i'm not sure what i should do without destroying anything.. and i'd rather use what i got. please help!!
