Please note that this is just IMHO, as I am not an expert by any means... however I am telling you this because I have previouslt ruined both... (non P cars)..

Good Luck

PS: as you know, you adjust the preload with different shim thickness
I second this.
My experience with ring and pinion gears is all non-Porsche, so FWIW, YMMV, etc.
But all of my experience says setting that lash (and subsequently the preload) is the crucial element to the longevity of the gears, and the amount of howl you'll get from them.
I know there's a technique with a dial indicator.... but I'm old-skool (and old) and I've always used chalk, or even a mist of colored paint, to identify the contact surface, and adjust accordingly. Lots of tutorials on this method online.
