Careful! I did the same Pertronix conversion. Make sure when you unscrew the points system from your distributor, to use a magnetic screwdriver, the last thing you want is a small screw down in the distributor!
I'll give you a kind of step-by-step process how to convert, but first, make sure you have at MAXIMUM a 50-60 Ampere alternator. You don't want to fry your electrical system with new 75-100 Amp alternators. The electronics of Chrysler, although from the 60's-70's, were NOT up to par with other manufacturers systems. They were more suited for cars from the 30's.
So once you remove the points system from the distributor, remove the condenser as well, with the wires removed from the ignition coil as well.
Get a good coil that can sustain the new pertronix system. Then from there its just remove and replace.
If your distributor cap is stock, I would upgrade to a standard motor products "Bluestreak" line --> Good quality products from them.
You have to use the Pertronix rotor that is given in the kit, if you put on the cap again and hear a kind of grinding noise from the distributor when you start the car, take a Dremel and shave down the metal tip on the rotor so it can clear the cap (not too much!)
Upgrade spark plug wires (Magnecore Wires are best), and spark plugs (NGK ZFR5N are THE best and remove the spark plug rings as well!)
Check you Ballast Resistor as well, and replace if necessary.
Generally if you upgrade to electronic ignition on a car originally with the points system, its a pretty good idea to go over the whole ignition and charging systems. Its like buying a new suit but wearing old, beat up shoes when you go to a party.
