A few have... but not as many as the lo-buck 3G swap.

It is a 95 or 130 amp alternator from the 90's fords. It is internally regulated, and only requires 4 wires to run. 2 of which hook right back to the alternator. So you really only have 2 wires coming off. The large charge cable, and the green/red exciter wire.
It eliminates all the old wiring, the Regulator and is a huge improvement in the charging system. You can grab the alternator and wiring from a junkyard for less than $30....

I did the GM 1 wire swap It was pretty easy and straight forward. It's been on for a couple years with no problems.

go with a 3 wire, 1 wire parts are hard to find. Also if you have an ampmeter you will need to install avoltmeter because you ampmeter will not work.

I went from the 3G to the 1 wire when my 3G crapped out, for the simplicity and cleaner look. I was running a aftermarket voltmeter so that was already done. I'm not sure what "hard to find" 1 wire parts you will need. I had to make a longer spacer out of some tubing I had laying around the shop. I understand wanting to keep it all Ford, but it was so easy even I could do it lol. I've been burned on too many junkyard alternators so I went with a new one. I still have a 3G on my 67 Mustang and when/if it goes I'll probably go with a 1 wire on it too.

However, PA Performance sells a voltage regulator which preserves its function: https://www.ford-trucks.com/forums/9...l#post12678807
