Rear gear ratio for a 99 p71

[quick vic]

:help:How do you find out what your rear gear ratio is , there is no tag to check.

Axle code on door jam,or count drive shaft revolutions to one complete 360 turn of tire.

I was told you can check if your rear end is posi or not , By jacking up your rear end and rotate your tire and if both spin in neutral it is posi is that true? thanks
