The ignition module that sits on top simply unscrews and you splice it into your distributor pickup, ignition 12+, coil + and a ground. Done. You could stuff 20 in the glove box. They're cheap and easy. The gm distributor it's attached to is the only gm specific part. The ignition module doesn't care if it's a mopar or a chevy, a V8 or an I4. The distributors pickup sends a sine wave to the module, then the module drops the ground to the primary winding in the coil when it determines the sine wave "crossing 0." Dropping ground in the charged primary winding in the coil sends a magnetic field through the secondary winding and this sends the spark to the plugs through a phenomenon called electromagnetic induction. Science!
I personally would go with an easy HEI or just a simple orange mopar box, or the a system that offers complete control of ignition timing with 3D maps.
