Found a easy fix for dog bone rubbers 4 hockey pucks
Keyhole saw them the size as the original rubbers push out the old rubbers keep the bushing. Drill the center for the bushings press the pucks one on each side the press the bushing in place the pucks are a little bit lager but the fit nice in the u shape brackets
Hint: drill 3 small hole around they outside of the pucks in nail it to a board before drilling
