FWIW. The Pertronics triggers off the existing lobes on the distributor shaft that opens the points. These are rounded off ramps.
Not as precise as the reluctor used in the Chrysler distributor which has a distinct sharp profile. Knowing how anal Chrysler engineers are, you can bet they tested and optimized everything before releasing it. I ordered a new 1972 Plymouth Satellite Sebring Plus in the fall of 1971 with a 318 snd spent the 30 something bucks for the optional electronic ignition. It was standard on the hi-po engines but not the 318. Only trouble I ever had was a pickup coil went bad.
With the intended use of the OP's car, it probably wouldn't matter much. The Pertronics is completely hidden indide the distributor and everything looks stock on the outside. The Chrysler setup would require mounting the control box somewhere. Not stock looking but in the Mopar world, generally accepted. Dual points require a little more maintenance and last I heard were a little difficult to find.
