Those builds have a transformer (typically behind the glovebox) that will knock your socks off if not properly discharged. They had a tiny wire wound on the gauge needles to light them up. I'll guess it is the most expensive OEM panel to restore.
I met a 66 Charger owner at a rest/smoke bench on pond side of Pop Century resort @ Disney World years ago. Resort construction on the opposite side of pond wasn't even complete yet. Nothing more than ducks and construction workers to look at. Don't know why I tossed that bit in. LOL. Anyway... We sat there and exchanged Chrysler instrument panel knowledge for well over an hour, until our wives had met up and started a joint hunt down. When they found us, they had already fingered out what we had in common to talk about.
