The ohms for the coils differ per application. Pertronix will show a range from .06 to 3.0 for their I II III conversions.
If I remember for 4 and 6 cylinder engines a 3.0 ohm coil is used.Chrysler electronic ignition uses a 1.5 ohm coil.
The Pertronix I uses the ballast the II and III it is by-passed and the correct coil for them is listed.
Most Likely you will have the common I kit. The stock Chrysler 1.5 ohm will work fine.
