That just gives you:
Rear Differential Fluid 75W-90 Limited Slip to GM Specification 9986226.
GM Part No. U.S. 89021677 and Friction Modifier 1052358,
in Canada 89021678 and Friction Modifier 992694.
It does not give you brands.
I have some Castrol 75w-90 Synthetic gear oil that I need to check before I change mine.
