I don't know off the top of my head if its a 10 or 12 bolt, I believe it would be a twelve however, I'll find out tomorrow and post that for everyone.

The 10-bolt can handle just about anything you throw at it, as long as you use the right axle, either the 8. Not recomended if you dont have the proper tools. I decided to put a posi in it.
