Simple lesson...(or, word to the wise).
Okay, your gonna play with a dual point, Mallory, or whatever. Heck, that's all any of us do with 'em, is play, just twice the fun.
Always carry a 'spare' condenser with you!!! If it goes out, your on the side of the road.
Research dual point distributors, and LEARN how they work, what they do. That will make things much easier on you. Their like anything else, you simply need to understand what your looking at, what to do with it, and how to make all the adjustments.
First car I had (63 Ply SF) sported a factory Prestolite dual point...yeah, I learned the hard way. It's also the best way. Nothing hard about it. I've used dual points all my life.
