TB problems

Howdy- I am taking the front of my 68 Cuda apart and am having a problem with torsion bar removal. Working on the right side. I got the adjuster bolt about halfway out with much difficulty. Lotta PB blaster and liquid wrench and a 3' breaker bar. It's really stuck halfway out and I don't dare reef on it any harder for fear of breaking the bolt. Wheels' brakes etc. are off and front is up on jackstands. Air wrench does nada. My 3 hour job has turned into 3 days. Any suggestions?
