Voltage Regulator Date vs Car Build Date

Jimmy,
Probably original...

Thanks Kurt. Kinda thought so but..........used to think my water pump and clutch were original too, and it turns out they are not. So it doesn't hurt to check.

Back in the day... My buddy and I used to troubleshoot electronic & mechanical issues on my 72 Chevy by swapping units and parts from one vehicle to another.
Sometimes stuff just never got returned to the original vehicle.
Maybe your vehicle once had a swap partner before 1982?

Just checked the date on mine - 9C for a 04B Van Nuys builts Z.   Pretty sure it's original...

Just saw this thread got resurrected. Hans, that's great to know your reg is March because your car is so close to mine in build date, and from LOS too. I ended up going with the 9C VR but because it needed a rebuild, I got a Wells solid state unit and plan to rebuild the 9C with the internals of the Wells. Have seen this done before and it allows the base (with numbers and date code) and cover to be retained. So it looks OE  and there's no adjustment required!
