ive had a few that bad, were i cut them in half cleaned hex pockets with pick and drive,soaked in trans fluid, put jack under bar 1/2 jacked on it till busted free ot cut bar again close to box and sledge hammered out front to back, with bar cut again close to box it wont absorb hits and easy to hit sqaure to drive out. heat never works to much metal there in hex pocket and dont wanna put that much heat there.
