If your rear was not a posi, it would be simple. Jack one rear tire off the ground, rotate tire 2 times and count driveshaft turns. The amount the driveshaft turns will be the ratio. Won't happen with a traction lock.

Yeah, that's why I gave him the speed/rpm/tire diameter method, Ray. It works no matter if it's open, posi or locked.
