It's just a set of plug wires, holy crap, you should be able to swap pretty much any off of another bike without a problem. In fact you can buy the wire at an autoparts store and even make your own in a pinch. I think the only important part would be the plug caps themselves (the long hard bakelite part). They are Bosch parts, says so right on them, and maybe that rusty old VW bettle out in your backwoods has some that will fit?
