I went out today and removed the ball studs from my old 51 steering arms. I was only able to remove the tie rod ball studs. The stud that the drag link attaches to on the left steering arm would not come out so easily. I am wondering if it is threaded in or not. However, it appears that one side is larger than the other (tapered fit). I can see the outline of the crack in the metal where the stud should separate from the steering arm.
