I have a TII S4 stock clutch-type diff in it's complete housing w/ half shafts just sitting in a box in my garage. It does NOT come with axles though; that's all you would need to have to rock out with this. Also, I knocked out the stock rubber mounts, so you can put in whatever you want.

150$ picked up in Temecula, CA. If you would like it shipped, I can do that as well, but you will be responsible for shipping costs.
