If converting from points, and no plan for later rephase, get a Pamco
If you also plan on buying a PMA at this stage, and no plan for later rephase, get a Powerdynamo ignition/alternator kit. This will replace alternator rotor and stator, regulator, rectifier, and the stock ignition altogether, including coils.
If you plan on serious tuning now or later, including rephasing, get a PMA with an external "hump" for ignition trigger (s) (Hughs, Sparx or any other) and an Ignitech programmable ignition.
