daul point dist. 4 / 273motors

recently i scraped a 273 engine out of 65 s cuda.
when i pulled the dist. it had duel points.
i was wondering how long chry.actually used duel point dist.
thanks

That is part of the Formula S package. I have just rebuilt one! I want to go pertronix, but they don't have a kit for the dual point. Anyone know how to modify or rebuild a dual point as a single point? i want to star stock looking.
