That N6477 or 411 or whatever looks like a part # for something, what is left after gauges and buttons to go into the dash?
Actually, it looks like a smiths #???
Dual gauge
Fuel Gauge
MPh
Tach
Heater
Washer
IGNITION
CHOKE
a couple of lights, red, green.
The reason I say a smiths, is the part # for a smiths mph is SN6155/10
