I am upgrading my tie rod and drag links to the modern end replacement. I have the 53-54 pitman arm, drag link, and right side steering arm, but I don't have the left side steering arm. It looks like if I remove the ball studs from it, the holes will be the correct size for the ends to fit in. Is this right? Are the ball studs threaded in or pressed on a 51?
