Threading in a 1 3/8"x 6 or 12tpi tap & pressing out the outer shell is one of the best ways to do this if you have access to a press or a good large vice, without damaging the torsion bar anchor. You DO NOT want to nick that piece with a saw blade. To remove the inner shell from the pivot pin, just hit it with a ball-peen hammer around the outer diameter of the pin & the inner shell will basically slip right off. I just used these methods 2 weeks ago & they worked like a charm. Look for Mopar Action Magazine tech info stuff!
