I got the halyard box rebuild kit from rig rite. They threw in the sheave pins, but I'm not sure how to make the new ones stay in the box. I figure I can drill out the old pins or drive them out, but Don't I need to 'peen' the ends somehow? I tried calling rig rite but they were no help. The pins have a small concavity in each end. Thanks!
