I just pulled out my front diff internals and wondering how to find out what gears ratio I have by looking at the ring. Any help?

I would have looked at the tag on the diff cover.

Jack the front axle up off the ground so you can rotate the ring gear. Count the number of teeth on the ring gear and pinion gear. Divide the ring gear tooth count by the pinion gear tooth count and you'll have your ratio.
