Which Pertronix did you buy? I installed first an Ignitor, then Ignitor II, on my 'bird. The Ignitor, which uses the reduced voltage from the resistor wire, took about 20 minutes to install including pulling the distributor. The Ignitor II was quicker on the distributor side, but required a 12v supply from the bulkhead connector to replace the resistor wire.
