If the coil that blew up said "use with resistor" or "electronic" they WILL blow up if installed where a standard 12v points coil should be. Get a Bosch SU12, not a SU12R. Or a GT40, not a GT40R. You can also use a transformer type GT40T. Again, NOT a GT40RT. To use a resistor coil you must also have an ignition resistor in the circuit.
