Not far from the 2.93   
"Gear ratios available on the 8-3/4" axle through the years include: 2.76, 2.93, 3.23, 3.31, 3.55, 3.73, 3.91, 4.10, 4.56, 4.89, 5.17, 5.57"

did you just turn 1 wheel or did both turn exactly equally ?

It got a posi rear, so both wheels at the same time...

In my 30 years of MoPar I only ran across 2.76 - 3.23 - 3.55 - and up...
It must be a 2.93 then...
