urquattro rear diff question

[aronmatic2]

i have to change the tranny on my urq. i have a audi 200 10vt tranny(i think aaj).
thats goes up temperarly for 6 months. that time i can rebuild the uri trans.
the question is. is the same the rear diff gear on the wr diff.
i dont remember, is 3.89 or the popular 4.11.

AAJ: 37:9 = 4.11:1
7Z, 4H, 5H: 35:9 = 3.89:1

So, URQ rear axle with AAJ gearbox = no-no
