How to convert points to Dura-Spark

I am pretty sure that the early duraspark's had a pickup coil inside the distributor, and the duraspark IIs had a hall effect sensor in there. The earlier units weren't used too long, and I think that they had an ocassional problem with the pickup coil failing when it got hot. Start and run fine cold, 10-20 minutes later it would fail like someone reached over your shoulder and turned teh ignition key off. 20 minutes to cool off, and start right up, only to repeat itself.
 
I was a little surprised that 80_Maytag said 6.5 volts, because I thought that they were 10 volts. I guess it varies by year.
EDIT: So I just pulled out my Haynes manual for the 1980 - 1996 Bronco's and sure enough the ballast resistor reduces the voltage to between 6-8 volts in run position.
