Fluid Capacity of 8.5" Rear?

[RKHiPerformance]

Can someone please confirm the fluid capacity of the 8.5" rear axle assembly? Does this capacity change significantly with the installation of a T/A Performance diff cover?

Thanks!

2 quarts of gear oil and 4 oz. of gm posi additive should do the trick...

fill it till it can't be filled anymore. That is the reasoning for the position of the fill hole.
