If you must run a Mopar electronic get a 4 pin ECU from MOPAR no aftermarket.
I run pertronix and points both in two different cars + electronic oin my trk etc the pertronix is troble free as are the points said it before and I 'll state it again when its time to change points it would be time to clean and lube a electronic dist about once a year or 2. I have seen too many elec dist with frozen or sticking advance weights or broken springs.The problem seem to center on the off shore pickup plates and the bad Mopar perf ignition boxes. Don't say you never had one go bad I have a collection of that crap. 7 boxes all perf all bad over the years
