NOTE: Some early model Onans  may require a separate bracket/hole modification to mount this style coil.  If your tractor still has the complete LONG cylinder looking coil that is completely circular from top to bottom long and skinny then you will likely need an adaptor bracket or hole modification.  Also note, all new replacement coils for Onans are non threaded for spark plug wires.  We recommend to swap out your wires if you do have threaded wires boot ends and it is also a good pratice to swap them out when you change the coil anyways.  There is an option at check out to add wires to your coil order.
