Quoted from redrock:There is a spring (A-13455) on the shaft only on one side. (Not to be confused with the two springs for each trigger.) Did I lose one or is one correct? The diagram in the parts manual suggests one is correct.
I just looked at my King Pin. It has two A-13455 springs, one on each side. I think only the shorter drop target banks (5 targets or fewer) use one spring.
