Petronix Electronic Ignition Any Good?

^^^ this right here.

i know if i'm broke down at the *** end of hard luck i'll be able to find a mopar EI box somewhere any time of day or night.

This is exactly why I don’t order aftermarket stuff.
I run 8 pin GM HEI from a recurved and centrifugal limited stock electronic distributor.
You can get that **** anywhere.
