Greg, Regarding your power pack assembly for the "electro-illuminance" it has been a while since I did any research, but there was no less than 6 companies that advertised in Hemming's that effect repairs on these units under Chrysler parts and service. The power transister goes bad.but can be replaced. I believe they were also used in the 66-67 Chargers also the early 300 series. Biff DeMartino
