engine build for reliability

Cap and rotor are the least of my worries. It’s circuit board inside. I bought an extra one for my RTR msd dist Incase. Wasn’t cheap though
Doubt you will find a stock mopar ECU at your local corner autopartsstore aswell..
I see what you are saying but what im trying to say here is that alot of times aftermarket parts are based on something stock anyway just takes alitle research,and i do see your point in wanting to have spareparts for every occasion,im that kind of person aswell.
