One of these days I'm going to convert mine.
The best way to do it is to swap in 78 or newer cruiser parts. The distributor and ignitor.
If you use the large bodied distributor from the later 2F, you will have to swap side covers as well.
One of the reasons I haven't done it yet is that the semi electronic system has worked so well. The points last forever, I'm still on the set I put in when the engine was rebuilt over 14 000 miles ago.
The way it's designed keeps the points happy, the points are only a trigger and the big voltage bypasses them, so they last forever.
But I'm also looking for a good used setup for my rig.
