According to a option decoder book i have, option code GU4 is a 3.08 ratio.... thats all it says... anybody tell me anything about it? good or bad? last night a friend 'provoked me' into doing a smoke show, well i basically did a rolling power brake and i noticed that the back end was swaying around a bit... which leads me to believe its posi....... i guess i havnt looked REALLY close but i didnt see a LSD tag on it and i dont REALLY wanna take the cover off to be sure, as far as that goes i can handle not knowing until i break it....

 

Option code G80 for posi.

 

i believe thats not one on the list. thanks for the info
