I have those Honda coils on the shelf, I usually buy them in threes on ebay. I have one mounted with the Napa ICR23 resistor on my unfinished bobber. You would still have to rewire your points wires as retired showed on the diagram for a dual output coil or try the dual lobe cam. When it comes my time I think I will try the two point, rewired, set-up.
Wires and boots, I always start with new wire from Napa, my store has 7mm metallic core, dark blue silicone wire by the foot, most Napa's don't have it, and new caps. I just can't see using old Briggs & Stratton type wires or old caps. Those NGK resistor caps are a great design but there are 6 connections in there counting the resistor, 6 different connections that can tarnish and corrode over time, the innermost connection is the worse, I've tried cleaning them only to find that the innermost connection is worse when reassembled.
Yes that's all you should have to do. Coil, resistor, rewire points, wires and caps. Oh yeah, condenser.
