For those who want to stay Mopar, consider the coil from a Magnum engine. It is E-core type, but more work to wire to a GM 8-pin module.
Much easier is to take the GM cables at the junkyard. One cable goes from the 8-pin module to their "external coil" - simple plug & play. You only need to wire +12 V to their thick red wire and use their tach output (white wire), if desired.
I did similar. Get the special pickup connector, snipping the GM wires right at their pickup coil. Wire to a double-bullet connector to plug to the Mopar distributor pickup. But, polarity matters (use a timing light to verify it sparks w/ reluctor teeth are aligned). Also, not all dbl bullet connectors work. Some have short male terminals that barely contact.
