We found the Shark camber strut-rod removal socket works best to hold the slotted center pin while swaging it. This prevents the slotted portion of the pin from distorting while under pressure from the press. The outer perimeter of the center pin should sit on the socket only, avoiding contact with the slotted area. The key is to lock the plates firmly in place without distorting them. We used a hydraulic press to lock the center pin in place.
