I will be going with the 8.8 rear too. I am already going to have to narrow the rear for the mini tub job and why not go with a nice light strong disc break rear end to start with. I can get one front the local PullaPart for $100 complete posi and all. And it's a swap you won't have to worry about if you are making big power like I plan to. I will also be keep the torque arm suspension for the "stock" suspension class legal
