Ernie,
This is my daily driver and it is green with a white top. It has a 289/2 barell carb and an automatic. I love this little car and just had the engine rebuilt after 152,000 miles. Needs paint as the parking lot wars have taken their toll.
Now that I know you know about them, I expect some help on this weird problem. It has been going on for a couple of months and doesn't hurt anything, but it is driving me nuts trying to pin down something that could cause all of this. I swear it seems like a ground problem, but what could afect all these different circuits like that. I was going to get under it today and do some looking at grounds but it is to cold and getting darker now. I think I have pretty well eliminated the regulator, (new one), and alternator, but am not positive about the alternator. However I don't see how that could cause all the gauges to not read for 20 or 30 seconds after I start the car and then all of a sudden they kick on. And the ampmeter flicking back and forth like that is weird as it is in series with the alternator and battery and not on any other circuit.

Sub Note: If I just turn the key on and don't start the car, the gas gauge will read, but the minute I start the car it drops back to zero until all the gauges kick in. Strange HUH !!
