I've seen 3.55's too I believe. My axle is a 3L73 = 3.73 Limited Slip.
All 95+ is the ones you want. All are 31 spline and all are disc brakes. Limited slip, open, gear ratios are all variable...so you never know til you look at that tag on the axle under the donor vehicle.
Generally, if the donor vehicle has a 5.0 in it, it's highly likely to have 4.10's and Limited Slip.
