Another differential fluid question.

Going to changing the fluids in my Dana 80 (LS) and NV4500. Plan on using Redline.
75w90 (w/ friction modifier) in the rear and 50/50 of MT-90 & MTL the tranny.

Question: How much fluid for the differential?
The Haynes book list the Dana 80 between 6.8 and 10.1 pints.

I plan on jacking each side of the axle up while the cover is off in order to drain as much old oil as possible. How much lube should I expect to use?
