Borg Warner ignition, need trigger unit

My "take" on ignition is that "you need something that you can fix on the side of the road."

This is why I used to run factory Mopar ECU, and now run a GM HEI module with factory Mopar dist. I can FIX it, and I can buy all the parts at any parts store

So if you stick with something (like Pertronix) that isn't a stocking part in the stores, ya better buy two.
