68 Cuda Upper ball joint removal - looking for help

What started as a disc brake conversion on my 68 Cuda project has turned into a little more. Having a problem getting the spindle off the upper ball joint stud, and also in getting the ball joint out of the upper control arm. Is it true that the ball join is threaded into the UCA? If so, do I just need a big enough socket and breaker bar to get it out of there? And how do I get the spindle off the stud? Thanks in advance for any suggestions.
