If I was in a junk yard looking for a 130 amp alternator and I was going through some on a shelf that were not marked and the guy who works there has no clue whats what how can I tell the difference between lets say a 89 and a 94 alternator? Is the 130 amp bigger in size or what?

Here is a list of vehicles that have the 3G alternator, most are 130A, but some might be 110A:
94-96 Mustang 3.8 V-6
94-95 Mustang 5.0
94-96 Thunderbird 3.8 V-6 (non SC)
95-96 Windstar 3.0 V-6 (most are 3.8's)
93-96 E/F series Trucks/Vans 4.9 L6*
96 Sable 3.0 V-6
94-96 Cougar 3.8 V-6
*Probably the best one if you can get it (should be easy to find, too) is off the E/F series...this series uses a

threaded top ear like the stocker on the Mustang....E/F series with threaded ear uses metric bolt. ALSO, make sure

the E/F series is 130 Amps and NOT 95.

Ok... thanks for that info. At least I know what else it comes on but that still didnt answer my question exactly. How can I tell the difference in a 75-95 amp and a 130 amp?

87-93 alternators have an external fan, right under the pulley.
3g's have an internal fan, viewable from the front.
