You either have the 3.31, or 3.55. For 2007, the 3.55 was optional, and cost $100 extra, otherwise the 3.31 is standard. If that doesn't help, you can always look under the rear end of the car, there is a tag on the rear diff. cover that tells the axle ratio.

1. is it auto or manual
2. if it is auto it is 3.31 or just type stock
3a. if it is manual check your window sticker
3b. if there is nothing then you have 3.31 gears
3c. if you see 3.55 gears on the options side then you have 3.55 gears
4. you can look at the gear housing under the car and there should be a sticker that says

Open the driver door and look at the dataplate. Find the axle code and that will tell you.

AXLE code:
BG = 3.31 non-limited slip, base vehicle with manual or auto
CD = 3.55 limited slip, GT with manual
CG = 3.55 limited slip, GT with auto

Sorry to differ, but my sticker says CG, and I have a manual with a 3.55 limited slip.
