I remember now... then VIN won't help you. I did check the ratio before I bought it. One of the codes reveals this information... its in the glove-box. This is not mine....
This guy has the 3.42 according to his build list.
Mine "was" the GT4. I think then, for 2010 all these were possible, from the factory.
GT4 Rear axle, 3.73 ratio
GU4 Rear axle, 3.08 ratio
GU5 Rear axle, 3.23 ratio
GU6 Rear axle, 3.42 ratio
PS: I had thought all the towing options, plus the 3:73 was what got me the "over rated" 9500 capacity.
