gear ratio confirmation

I purchased a used D30 from a 95 YJ. I am in the process of tearing it down and freshening it up for install into my 93. Just want to confirm it has the 4.10 gears in it.

Here is a pic of the ring gear.

You can count the revolutions of pinion vs axle flanges.

Ok. I've got the axles removed...so reinstall. With both axles "off the ground" count pinion turn vs axle turns....I seem to remember having to have the axle spin twice..that sound right? What's the method?

One wheel revolution to however many driveshaft revolutions. Or in your case its pinion to axle flange.

You can do it twice and divide by two, yeah.
