3g/6g How do they look different?

I went to carquest and told my buddy to get me an alternator from a 00-04 V6 Mustang because it should be the 6G alternator. Upon bringing it to my house and finding out what a 6g looks like, it does not look like the one I have.

Mine looks like View attachment 379803

Except that it has a gray housing for the plug, and not a white one. It has two electrical plugs, one I THINK is for the stator wire, which is supposed to be elimated on the 6g alternators.

It looks nothing like

Which is a 6G alternator...did he give me the wrong alternator?

What's so much better about the 6G than the 3G?

It is my understanding that you do not have to grind the bracket for the 6G and it has less rotating mass.

The 6G alternator runs cooler/more stable and has less rotating mass (frees up HP) compared to Ford's previous models(3G). And the alternator does not require that the bracket be modified, it bolts directly in.
