I need to install one of these alternators and I was wondering, is there any other cars they come off of besides the 94 and 95 Mustangs? If so, will the bolt up the same way?

Thanks

They will bolt up the same way but you need to grind a lil bit off the alternator bracket because it hits. You'll see when you mock it up.

I forgot to mention. The stock alternator has the top ear threaded so the bolt threads into it. The 3G does not have a threaded ear, so you will have to buy a bolt and nut to hold the top of the alt in place.

Yeah, I knew all that stuff (thoroughly read through the article on corral), but what I was wondering is can you only get these alternators off a 94 and 95 Mustang or can you get them off say a Taurus or something like that? I am heading to the auto wrecker tomorrow to look, and the more kinds of cars I have to look at, the easier it will be to fine the alternator

Also measure the distance from hole to hole in your stock alternator so you dont get the wrong ones

Here's websites with pictures of the 3G installation...

See http://www.geocities.com/smithmonte/Auto/3G_130A_Alternator_Upgrade.htm - all the tech data you could ever want to know
OR
http://www.mustangcentral.net/tech/alternator.html - excellent pictures of installation

For the right way to do the wiring. Some people will tell you that you can skip the wiring upgrade, but it will catch up with you sooner or later. A fire in the wiring harness is ugly and expensive.

Under no circumstances connect the two 10 gauge black/white wires to the 3G alternator. If the fuse blows in the 4 gauge wire, the two 10 gauge wires will be overloaded to the point of catching fire and burning up the wiring harness.

One on the sites has a list of cars with 3G on them.
