75w90 or 80w90 will work fine. Remember LSD gear oil is only for clutch-type LSD's. If you have an open diff OR a torsen you should use normal gear oil.

GM LSD fluid.
2 quarts of your favorite 75w-90. I was going to use Mobil 1, but I never got around to swapping the fluid in the stock rear before swapping the entire rear.
