Chrysler offered electronic ignition as an option in '72 and it was standard across the board in '73. Like the advent of fuel injection in '88, it cut warranty claims by a massive amount. I'm not sure about '73 but warranty claims for '88 dropped 80% with the advent of fuel injection. Chrysler offered F..I. in the early 80's but it wasn't a very good system.
If you think the ballast resistor is bad, use a jumper wire across it. If it starts, you have a bad ballast resistor. Back in the 70's, myself and everyone I knew who drove Mopar's kept an extra ballast resistor wrapped in a towel in their tool boxx.
