I will say a pertronix coil can be run with out a BR. been running mine that way for 17 yrs now.

BUT.. I have a points dist with a pertronix points conversion/pertronix chrome 40,000 volt coil in my 68 Dart,now in my 85 truck.

BR by-passed with a jumper or a #10 strand wire/solderd spades in the BR shell to hind it.

my 88-440 truck will be getting a old skool mallory duel points dist with a pertronix points conversion in it with the chrome 40,000 volt coil as well.

I remove all the stock ecu/elect crap.
