If you've ever done a 1:1 diff you'll know what I mean.

I don't think anyone makes a small enough dial indicator to set the backlash
It is important to see the mesh pattern, but generally a full size vehicle is set that way to minimize noise. It does help longevity... But a properly shimmed diff will do just fine. I generally set the pinion depth so that the teeth match up with the ring as evenly as possible, and the diff cup does not rub on the end of the pinion.
