It is either the 2.73 or 3.15. I believe the rear end is tagged with the ratio or you check your glove box. Check for either one of these codes:
GU2
Axle, Rear, 2.73 Ratio
G90
Axle, Rear, 3.15 Ratio
GU2
Axle, Rear, 2.73 Ratio
G90
Axle, Rear, 3.15 Ratio

A few yeas back someone posted a quick way to do this. I think it was something like this. Get out on the highway and put the transmission in 3. Get up to 75 mph. If your tach is at 3150 you have a 3.15. If your tach is 2730 you have a 2.73. I just went out and tried this and I know mine has a 3.15 rear end in from the build sheet. It seemed to work as I was turning 3150 at 75.
