I have a 99 Z/28 6spd and I'm wanting to put 4:10's in but I have no idea what carrier it has or the size of ring gear I need. Anyone wanna help me out? A link to a sponser who has them would be sweet.

 

A 2 series carrier is a car that came with 3.08s or lower from the factory (i.e. all of your 2.73 cars). A 3 series carrier is a car that came with 3.23s or higher. This is very important when you order new gears, as they will differ from 2 to 3 series carrier!
