Hey Glenn- I have no idea but some food for thought, you have an external cooler for the rearend on your ZL1. With that being said, the oils may be different. We know the gearing is different, but I'm not sure about the rearend itself.
It's a very interesting question, and I'll be following this thread for updates. It wouldn't hurt to take it the dealership, that way you have a record and paper trail of it.
I know it's no help, but the posi unit in Jade makes a slight noise when you turn sharp, but I set the clutches tight for straight line launches.
