Does anyone know what gears i have?
You are missing the first 2 or 3 characters on the second line but your tag says either :
S3 409 H
3.73 10 5 0F08 or
S3 409 H
3L73 10 5 0F08
The S3 is Sterling Plant
409H is the revision number
3.73 is the ratio
3L73 is 3.73 with limited slip
10 5 is 10.5" ring gear diameter
0F08 means this axle was made June 8th 2000.
