The Hot-Spark is for Datsun 1200-style Hitachi distributors. It is only $50 USD, and fits easily like a Pertronix Electronic Ignition unit, but is less expensive.

It should work on your 1200, assuming you have an early Hitachi distributor (D4n type) and not a Mitsubishi unit. It will say on the distributor housing. Look for D410, D411, or D4A markings.
As with any points-replacement system, you can use the stock points coil with the stock ballast resistor. Hot-Spark sells a HS34HEC "high energy" coil, but it is a low-current 3.4 ohm unit. Electronic Ignition Coils are usually 0.7 ohms for a more powerful spark, but that is not compatible with the Hot-Spark.
Coil must have 3 Ohms or more primary resistance.
They also sell a new distributor (HS-HIT4) for L13/L14/L16/L18/L20B engines.
