My First Mopar- 1966 Barracuda project

Looks great, like your thinking on the door panels. Just a suggestion, eliminate the mechanical voltage regulator for the gauges and use electronic regulator(s) bench test the gauges before install. The electrical on the printed circuit board is crappy and prone to cracks if you need to take it on/off. Replace it with a multi pin connector with
a pig tale this way easy on/off. Good luck!
