Larry,
I did just what Alvins pictures show. I used a dremell and ground the bottom of the ball stud, the stud is flared out. I ground around the outside edge till I could see the center of the ball stud. Then a long punch and a 3lb. mall and a few well placed hits and it was out. Might have taken 15/20 minutes to do both arms.( I had two extra arms off of another front end)
