742 case setup help

I have a 742 that I have gone through twice.
The gear patterns look fine, but when I checked the gear mesh I had the pinion nut more than just ‘snugged’. I ran the torque up to 125 foot lbs, just to be sure the bearing were seated.
Are you using the same shim set up as the prior ring gear or have you worked you way into the current set up?
I don’t remember the back lash spec. So I don’t know if the .007 is good.
