what carrier is a 97 z28. is it a 2 or 3 carrier?

 

Depends on the tranny, and what options the car came with. Base A4 with 2.73 (GU2)gears had a 2-series. The "high performance axle" A4's (GU5) anhd M6's (GU6) have a 3-series.

"Drivetrain" is the correct forum...... moving it there.

 

i have 273's

 

2 series = 3.08 and numerically lower, 3 series = 3.23 and numerically higher.
