[37 Cab]

I am planning to put a set of 3.54 gears in my 37. I have done a ton of late model rear ends but never a banjo so this will be a learning experience for me. My question is about pinion depth. I have read a bunch of posts and the only clearance adjustment I can find is for the backlash. I understand the preload and backlash adjustments but the pinion adjustments are a mystery. I assume there are specs and adjustments for pinion preload and depth but have not found any info on it.. So.. how do you adjust and check pinion depth? Preload I am pretty sure I will figure out once the parts are in hand. Any help here appreciated.
