If you open the glove box you will see a mess of these the digit codes.
About the 4th or 5th row over you should see a GU6...

Hey! What Tony H didn't tell you that the GU6 refers to the 3.42 ratio! Most likely with the 8.5 ring gear-the best of the stock bunch:stout and good fuel economy! But I don't know the other axle codes...sorry! W3

thanks for the info guys!
but i didnt see anything with a GU6, all i found that started with a "G" was GT4 or G80

GT4 is the code for 3.73 and G80 is the code for the limited slip/gov-lock differential.

i figured it out, 3.73 Ratio = GT4 : G80 = limited slip.

If anyone find any info other wise please feel free to correct/inform me =]

OH MAN!! I left out the actual reason for writing it. Thanks for filling in the blanks.
