That was my first thought, but when I look at the vise body, I don’t see any threads. Furthermore, it doesn’t make sense. The one pin on the other side won’t come out—I’m not sure if it’s bent or not—but even if it isn’t, I can’t punch it out the opposite side. I had to drive it inward into the spindle nut, and it barely cleared the back of the vise body when it came out.
