I'm trying to determine the axle ratio in my 1995 Z28; I am the 2nd owner
without contact with the first. I understand that there was an optional gear
ratio available and would like to determine which one is in this car. I
don't know whether I have the 2.73 or 3.23. Can anyone here tell me how to
find this out?
I'm seeing some RPO definitions (whatever that means) as GU4 - GU6 from a
parts manual. Are these codes from a VIN? I'm wondering if the information
I'm looking for is somewhere on the car itself. If I can get a clue as to
how these codes are read, I think I can figure out much about this vehicle.
Thanks for any help....
