1969 Swinger 340 distributor questions

unless your trying to make your 340 origional i would stay with electronic ignition. Stronger and more reliable spark, easier startups, no points to mess with.
I'm trying to put the car back to stock as I'm restoring the car. I want it to look like it did when it was made.

Anyone have any info about the voltage regulator or the ballast resistor I posted about?
This is all new to me because I'm a former Corvette guy. I can tell you what is original and stock on a 69 Corvette down to the last detail, but on a 69 Dodge I'm completely out of my element!
Is there a site I can go to that will help me learn? I have the shop manual, and the wiring diagram, but neither show these parts in detail nor their location on the car.

Thanks again guys.

George
