Pertronix rtr distributor vs. ignitor III

Well i decided to go for the HEI. Spent a few hours at the junkyard today, found a 4pin hei module and the appropriate plug/wiring, which turned out to be the hardest thing to find. By a stroke of luck on my way out i ran into a dodge truck(that was in pieces) and it was the one dodge in the lot with the plug i needed.
