Few Rearend Rebuild questions

[429mustang]

I swapped out a set of 4.10's in my friends car for 3.73's. I figured out how to use the proform pinion depth gauge and the pinion is in. First, my inch puond wrench is in increments of 25in/lbs, and the pinion drag is probably around 10-12 with a new bearing. Will that be enough being I used a solid pinion spacer setup? I figured everything probably seats slightly tighter since theres no cruch sleeve to absorb any clamping force when torqueing the pinion nut. Also, I'm gonna set the backlash/preload tonight. I've checked out a few buildups but If anyone has any specs/tips on the order I should set up the last two measurements I'd appreciate it.
