Performance Axle code

Where can you find which rear axle you have on the A4's? As I recall, there was a sticker or something in the glovebox w/ the option codes. What code should I look for for the 3.23 rear axle?

On the edge of the driver's door:

GU2 for 2.73's (come standard with automatic)
GU5 for 3.23's ("performance" axle for auto's)
GU6 for 3.42's (standard axle for 6-speeds)
