Your using your same transmission? then you don't need to do anything about axles. The onlything I see that you'll need to change is the mount that attached to the front of the engine pull the one off of your Z6 engine and put it on the Y8. If the Y8 for some reason is from an automatic you'll need to use your Z6 Intake manifold. Automatic Y8's used a 3 wire Idle air control on the Throttle body and don't have the holes on the back of the manifold for the 2 wire setup. Hope this helps.
