Pretty sure it was "some" in 72. I bought a low miles 71 340 in a junk yard, back "then" and swapped it into my 70 RR. It had a Prestolite dual point, which I still may have.......somewhere. The 72 shop manual wiring diagrams depict both breaker points and treat the electronic in a separate diagram......as if it were an option. The C barge seems to show it native, the diagram for the Val shows points
