So with the gauges dancing like they do, all at the same time and in the same direction would it be the alternator or the voltage regulator???

I would check all the Grounds and clean then all up even if they look good.
The check the cables from the alt. and don't forget the battery terminals.

Usually a grounding wire.
I pulled a ground wire on my truck that was connected to the exhaust manifold and forgot to put it back on when I put the header on, and the guagues were all 'off' a bit, and much more volitile.

I'll check the grounds the next time I'm out working on it, I know the terminals are good because I just cleaned them when I put the battery in...
The needles sweep from their correct positions all the way to the right side of the gauge, usually happens when "adjusting" the rpms...

There are several types of dance
gauges are ......sweeping from left to right and back !
Rapidly, slowly, fully/halfway.....etc
You can have a bad ICVR, bad ground for the cluster, bad connection from the starter relay LUG, etc
Can you film it for me ?
My guess is a bad I.C.V.R.
