8 3/4 742 build up

Ok I need some assistance from the aall telling mopar group.
Building up a 742 carrier, new everything. The original pinion had the spacer under the rear bearing (caliper broke so I need a new on to be precise) looks to be the std .090 one. there was a thin shim on the shoulder of the pinion under the fwd bearing. There wasn't a spacer on the pinion.
used the same setup with the new pinion, when setting up the preload it takes about 85 lb/ft of torque to get 30 lb/in of preload measured on the pinion nut., installed the sure grip, set backlash to near zero and got a good pattern, (painstakingly honed out the original bearings to create a near slip fit for setup).
When reviewing the torque requirements, it was 200 lf/ft for the pinion nut (have the torque values in my shop not in front of me), if I torque to 100 lf/ft the pinion will be locked up tight, no way could I ever get to 200.
What am i missing here?
