There are still ignitions out there. You just gotta look real hard and be prepared to pay for them. Either that or buy a Dyna and modify it voiding all warranty..
Come to think of it I think you can buy a Hondaman ignition that still uses the stock points but only as a trigger, essentially making them last forever. The points I mean.
Additionally, Boretech offers an ignition.
I've started my own little collection amongst my NOS parts stash.
