Has anyone tried to wire in a 3G alternator into a classic Mustang? I found a webapge that shows how to wire one into a early Bronco which should be the same.

Just wondering because I might try it...

Apart from having fewer wires floating around (or so the link says), what's the advantage of doing this swap? Simple terms please -- I'm pretty ignorant! I have a Nippon Denso alternator that works just fine, but I get tired of people looking under the hood and sneering

I did this on my 67 about six
months ago, it bolted right in, I just had
to buy a new wiring harness for it, which
was about 7 bucks, the junk yard
sold me the altenator for 30 bucks,
and let me have a single groove pulley
from a different altenator, since I chewed
my other one up trying to get it off without
the proper tools. You should just go to a
local autoparts store to have a look at
one, just ask for an altenator for a
3G altenator for a 95 Mustang, which will
be the same as the one I got from the
]junk yard which was from either a 94 or 95
Tauraus. The 3G's for the 4.6 liter cars
won't fit, they mount differently.
As far as the other question, the 3G altenators are rated at 130 amps, some of them are only rated at 105 amps though, such
as the ones for the minivans, which it would
seem like the would put 130 amps altenators in those. the stock altenators out out
around 55-61 amps I think. At the same time
I found an electric fan from a 95 crown vic
cop car, wich the blades actually measure
19 1/2 inches wide, I had to hack the shroud a bit to make it fit properly, but it swallows up the radiator, well since that fan
uses 30-40 amps of power, and I have a
few other high poered eletrical items,
I needed the stronger altenator, thats the
