I doubt one will ever cross my path but if it does, anyone have any idea what they're worth?

I'm curious also if the oil pressure gauge is mechanical or not. I suppose the idiot light trace is there and they could replace the sensor.

Basically, I'd like to learn as much as I can about the 1969 gauge package. Was it ONLY available with the 140mph speedo? Did it come with it standard? Could it be had outside of police cars? And so on... any and all trivia!
