Suggest you call Pertronix and ask them.

You need to get the correct parts according to the distributor number on the tag. Don't go by make and model year. And like Don said, when in doubt give them a call with that distributor ID number.

Agree. Get the correct unit with a matched coil and it will be fit and forget. This is a sweet set up.

I also suggest using their plug wires, or similar suppression plug wires. Old style solid cores will mess with the module.

Really? I've set myself up for a downfall this whole time then. Got the laquered wires on there...

Pertronix does make some nice ignition wires - stainless steel wrapped core. And the outer jacket insulation is black, not bright yellow, blue, or red!

I have no proof of this, but it seems that every story I've hear regarding a Petronix failure, they were still using old solid core wires. Some of the theories I've heard is that they can create electrical interference that can cause issues with the electronic module.

Good point, makes sense. I'm about due for a new set anyway, and I never was really fond of the stock lacquered wires. So far though, my ignition system has been working well.
