The small case for what I have read came with an output of 95A, only the big cases were rated up to 130A.

The ones with 2 holes AREN'T small cases... The one with 4 holes has a 135mm radius (small case), the ones with 2 holes have a 148mm radios (big case) both are 3G alternators.

Yes, that's a great link, please do take the time to read that.

I wasn't "suggesting" that I pulled a small case 130 amp alternator from a 3.0 taurus, I was "telling" people that's what you do.

Here is a picture of my 130 amp small case alternator from a 3.0 taurus



pic of the output with the sticker on it that says "130 amp"

this is a picture of a "large case" 130 amp alternator...note the 2 holes between the ribs on both...note the mounting ears on the large case, that's how you tell it's the large case...these larger ones are easily found on the 3.8L taurus



this is just a picture to show what the 95 amp units will look like...this is a 4 hole 95 amp alternator on a 5.8 engine I picked up...these can be picked up with the small case configuration too, so when you're at the junkyard, pay attn to the holes between the ribs

This is what I corrected you for, there is no such thing as a small case 130A alternator in the Taurus. There simply isn't a 130A small case 3G in any Ford vehicle.

Large cases aren't differentiated by the mounting ears or hole positions, but by the number of holes between the ribs, and most important, the diameter of the case's transversal section. The one from the Taurus you posted has 2 holes, showing crearly that it is a good old BIG CASE 130A 3G.

the 3.0 Taurus came with the small case alternator...no debate..that's fact and its linked above too in that article....the pics I posted above are my 66 mustang engine bay and that's a small case 3g alternator from a 3.0 v6 taurus...edit OK were talking about two different things...my definition of small case came from the above referenced article where he calls the unit with the bigger ears the large case and the unit with the smaller ears like mine small case

Well for the sake of proper information I had to correct the info you were giving (this isn't meant as a personal attack, I do know we sometimes read stuff on the boards and assume others are right), check this link also, it's from an alternator sales site:

How to tell if your Ford 3G series alternator is large or small case
