ironwill,
That looks like a dual out put coil that would work with a single points, dual lobe cam or twin points tied together, or the PAMCO, but I think that the price is a typo. If you click on the Shopping Cart button, it comes up "Out of stock". Maybe a few of them escaped at that $5.99 price!! (and maybe someone got fired too!!)
If you have to have a Harley coil, then the 17131 for electronic ignition with 2.5 Ohms or the 17130 for points with 4.5 Ohms is available from Custom Chrome for about $40.
