UCA BUSHING REMOVAL/BALL JOINT BOOT QUESTION

I have an air hammer, will try to get on it from the back side of the outer bushing flange. If not I'll try cutting it/folding it. Sure seems easy to mess one of these arms up in the vice while working on it!
Heavy washers,....large heavy washers.............. Oh, and get two more nuts, lock them together and use them to keep the threaded rod from turning.
yep double nut it
