Hi all,just got a '94 Z-28,I had a '95 4 years ago before I went ford.I loved that Z.The '94 is for my daughter for school,but I can't help but want to do some stuff to it. I remember there was a code in the glovebox sticker that let ya know if the car had the 3.23 axle ratio.Anybody remember it??Thanks, Randy D

 

I'm pretty sure it's GU5.
