Yep, not as easy on yours as if you had an 8 or 9 inch Ford. Those have drop out pumpkins, on yours you have to go in through the access cover on the back and install and shim the gears. Check Richmond Gear, I think they make a limited slip setup that can be installed on yours. The Camaro I am looking to buy has a 10 bolt and a Richmond Gear decal on the side, so I suspect they have what you need.
