You have 26 spline axles. You probably have 2.73 gears. You can check the RPO code sticker on the bottom of the console lid and it will tell you what is in it. This is all assuming that it still has the stock original rear end in it.

If you can afford it I recommend going to a 3.42 gear and a Eaton Posi. Don't forget to get a good installation kit.

 

Ok, well I found a guy with a powertrax locker that's still like new that will sell me it for $150 that will fit my 26 spline axles, so this should work fine right? Also does anyone know if it wil take my stock gears for now, or will I have to buy different ones right away?

 

The Power Trax will work just fine with what you have now.
