Ive removed my shifter to do some short shifter modifications. Upon pulling it apart so I could weld an extra length to the stick, I found a green bush for the pivot ball, obviously located in the shifter housing which unbolts from the gearbox. It is quite cracked up and looks like it probably should be replaced. Does anyone know where I can source a new bush? Tranny is an R151f, I assume the bush could be simialr to an R154.
