When I read about alternators in my service manual, I read that the diesel alternator has two wires, and the gas engine alternator has 3. The 3rd wire is the stator circuit. The stator functionality is internal to the diesel engine alternator and external to the gas engine/alternator..
I really don't understand what the stator circuit is, where it goes or what it does, but that does tell me at least that there are potentially different voltage regulators in similar alternators.
I can look up more this afternoon after church if anyone would like.

S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal externally from the generator stator to the regulator. This
voltage feedback signal (typically half the battery voltage) is used by the regulator to turn off the charging system warning indicator.
The gas engines have an external stator circuit and the diesel engines have an internal stator circuit.

I don't know if this helps, either. But this is the listed part number in the service manual for the alternator. The service manual only lists the single, and the upper and lower dual setup part numbers, not the gas one. But if you look this one up on www.partsguyed.com it specifically states diesel. Another indicator that there is an internal difference between the diesel and gas alternators.
The part number is 4C3Z10346AA.

But a 6G alternator is still a 6G alternator be it large frame or small frame......at least from every source I can find.....and still uses the same internal regulator so it should still work it's just a difference in what commands the regulator to say charge, correct?

This is the only "regulator/brush holder" assembly offered for the 6G alternator large and small case that I could find: National Quick Start Sales, High output alternator, Alternator & Starter Parts - Brush Holder Assembly
"Regulator / Brush Holder Assembly. Fits: Ford Family vehicles large & small case 6G Series Motorcraft type alternators. This is a generic number so when you order this product you must give year, make, model & engine to properly match the type you have."

I found this page in my searching. http://www.rcpcanada.com/catapage/Ford%206G%20Flyer.pdf See page 2. Also try this linkhttp://www.prestolite.com/literature..._Sell_Book.pdf page 5. I'm going to try to get a regulator for a 2005 6.0 and put it in the 135 amp Windstar alternator and see how it works. Wish me luck...I'll report back with my findings.

Little tidbit here; the stator is the stationary windings in the case and the rotor is the rotating mass. The rotor cuts the line of emf in the stator thus creating your a/c voltage source. Hope I explained that correctly, sometimes what I write and what I'm thinking aren't fully compatible.

I got my new regulator this week and installed it in the large case 6G out of the 99 Windstar. It works. From what I have read, it appears that the newer regulators are backwards compatible, meaning that a new regulator will work in an old application, but an old regulator won't work in a new application. FWIW the Windstar had a white regulator and the newer ones are gray.
I have one question though. Does the PCM control when the alternator kicks in to prevent frying the glowplugs?
