Pop bumper armature links: which to use and how they go together
The steel link breaks most often. The old Gottlieb link is no longer made, and the Williams 01-5492 steel link that fits is soft and also breaks, so it isn't recommended. The current hardened Gottlieb link is slightly larger: grind it down or notch the sides of the bumper bracket. On assembly, the bakelite spacer goes nearest the rod and ring nuts, the steel link bears on the metal bracket, and the two links' openings face each other from opposite sides.
