That's the plan man. I'll take a look at the 8142. After talking with my old boss, a retired SCCA Trans Am racer, he said most of the cars he had worked on had Denso power. Very few still used the CS series GM alternators.

I'm really excited to get the Holley dash. '66 Charger gauge cluster has been a PITA for my entire ownership of the car. A couple of hard launches and the electroluminescent or whatever they are called lights would develop a circuit disruption due to dash flex (my hypothesis). Then of course you get shocked with 200+ VAC trying to sort the issue out. No more of that distraction to going fast lol.
