OEM LSD in a Touring
 

One of the trade offs I decided to take with my new Z was opting for the Touring package for the uplevel interior pieces at the expense of the Akebono brakes, SRM, and the LSD. I also figured that I could add those down the road as my driving ability improves so that I can take advantage of the capabilities of this car as I go.

Is it a drop in swap for going from the OEM open differential in the Touring models to an OEM LSD from the Sport package? The diff doesn't look super easy to access at first glance but how much should I expect to pay for the install of the OEM LSD?

Thanks! The car is a 6mt btw.
