I have the opportunity to buy an 8.8 rear end housing off of a friend for $100.00. I want to build it with a Posi Differential and 4.10 gears. I'm new at this, so I have no idea what parts or materials are needed to complete a task like this. Is there a list anyone could point me to a list that would outline everything needed to build an 8.8 Rear End? Just to clarify. The bare housing is what I would be buying. It comes with nothing.
