Rear end oil capacity and type?

[mr_tinkertrain]

Ok, what kinda gear oil should i get for my rearend? and how much? I've already got some friction modifier just need suggestions on kind of oil.

3 quarts of Redline 75/90W w/ that bottle of friction mod. Kinda expensive stuff though but really good oil.

Correct... or 80W90 will work just fine. One or the another in synthetic is the way to go. Usually the 8.8 take's a little less then 3 Litres although it's pretty darn close.... fill it till oil just starts coming out of the fill hole and you'll be good to go.
