Here is what I did with my 79 Volare. Bought a aftermarket HEI distributor off E-bay(new) for 78.00 delivered and hooked up two wires to the coil and drove off. By far the easiest. The distributor has a GM style module hanging off it so you have to clock it correctly for clearance. I have no idea how long this distributor will work but it looks as nice as any other I have seen. They are still listed on e-bay. Search for Mopar HEI disributor.
