Fourth Generation Camaro RPO Codes ... GU2, Rear 2.73 Ratio. GU4, Rear 3.08 Ratio. GU5, Rear 3.23 Ratio. GU6, Rear 3.42 Ratio
Will say in your door jam or/and in your glove box on a white square sheet with SEVERAL other codes along with it. just find GU2, GU3, GU5, OR GU6 somewhere on the sheet.
But M6 all come with GU6 3.42's from factory....
