I'm going to go ahead and replace my Pertronix Ignitor I in the Coronet, as I think that's the source of my recent problem, and I'm trying to decide to replace it with the same unit, or step it up to the II or III unit. Anyone have some additional insight they can share? It looks like the III unit offers Multiple Spark Discharge. Each unit is about $25 more than the previous model. -- Bill M 65 Coronet 500 'vert http://1962to1965mopar.ornocar.com/mmo62008.html http://www.marylandmopars.net/membersrides/Bill-MelissaCoronet/Bill-MelissaCoronet.htm 73 Dart Sport, 00 Cherokee Sport, 01 Dakota SLT 21 Model T Depot Hack, 92 Accord, 06 Mazda 3 ---- Please address private mail -- mail of interest to only one person -- directly to that person.
