Rear servo parts: had to unbolt and remove the overdrive extension housing to access the rear servo anchor pin. It took some even prying to remove from the case.
Does anyone know if the rear servo spring and spacer is a "must do" item? I,d like to avoid pulling the overdrive section off mine if possible.
