I installed a Pertronix kit in my 66 273 HP with dual point about 3 years ago. I used the one for a 340 dual point if I remember right. It all fit right and works well.
I'm converting the distributor on my 67 Barracuda Commando 273 w / dual point distributor to electronic. This is an all original car that I purchased new in 1967. Distributor is Chrysler # 2642242 IBS - 4013 - A77.
Is this the same distributor as on your car that you converted? Tech rep at Pertronix told me there is no conversion for this distributor. What conversion kit did you use #1383 ?
