Just use Echlin points and condenser. They are original suppliers to Ford.
Considering the location of the distributor in the Pantera, why use a Petronix that does not have a stellar reputation for dependability?
If the solution is to carry an extra Petronix in the glove box, that's fine but if the installed one fails, you are going to have to install the spare. How are you on installing them on the road?
Traditionally, you should get around 30,000 miles on points before they need maintenance. Are you going to put that mileage on the car?
I've already been in the distributor twice in my GT350 for the Petronix that I was using. I am no longer running it. It runs MUCH better with the dual point distributor.
What you probably want to run is a Motorcraft Duraspark distributor and system in the Pantera. There is no dependability issue there that I am aware of. You likely will never have to look at the ignition system again if you do.
If you follow this website, we have said that over and over and over again. That is not an alternate reality.
