I'm trying to source new leaf spring bushings for an old 1978 jon boat trailer and I'm having a hard time finding them. They are a two piece bushing (One on each side of the leaf spring eye) that has an outer flange on them. The outer flange thickness is 1/4", the O.D. is 7/8" and I.D. is 1/2". The leaf springs are the normal 1 3/4" wide, but the connection point to the trailer is 2". The difference is made up by this outer flange of the bushing on each side. Do any of you guys use these type? Is there an alternative style or type that I could use without replacing my hangers? Thanks in advance.
