I am taking my 72 850 out of storage and getting it back on the road. I read what I could find on Pertronix Ignitions (+ and -) and have decided to go ahead and give it a try. The distributor is a Marelli S156AX. Ignitor or Ignitor II? Pertronix matching coil or any good quality coil? Plugs? Does anyone keep these in stock? Jegs and Amazon (from Jegs) are saying there's a 3 week wait. I'm hoping that a Fiat supplier might keep some on the shelf. Thanks.
