I had to do this also. I was not fortunate to have access to a press and am a rookie at this. However, I was able to work a larger wheel puller through the torsion bar opening and pushed the rubber and pin out. I later learned that you need the cup when using urethane bushings. Ironically, my method had not removed the cup and I was able to reuse it without removal. If you plan to replace with OEM rubber than you'll have to remove the cup. I saw an article in Mopar muscle that included tack welding a washer onto the cup which made for a point to pull/push.
