Little help needed. I started to change ring and pinion to my Camaros rear end. Instruction say that pinion installing depth is printed in pinion. for example 2,46" from pinion face to axle center line. Markings in my pinon says 108.16

So instructions arenīt accurate. I believe that is installing distance and in millimeters but from where it supposed to be measured...? Behind the pinion gear from bearing surface to axle center line maybe?

You need a "pinion depth check" tool to utilize those numbers and it associated system.

Paint and a little manual labor works too...
