PML Differential Cover Install

I installed a PML Diff-cover on my Moose yesterday and thought I'd let you all know how it went. I have the AAM 10.5 Diff. The cover looks awesome installed. The installation went well with the following glitches.
I had the gasket upside down at first. You know its wrong because 2 of holes will be off by 1/4 in. Flip the gasket and the holes line up perfectly.
Cleaned bolt holes with a tap and used blue thred locker on suppied allen head bolts. One bolt didn't want to torque to the 30 ft/lbs spec'd in DC manual. PML instructions say to torque to 15 ft/lbs or to factory specs if they are higher. It may be that my older wrench needs recalibration. Its a 20 year old (but good) Craftsman 5-75 ft/lb wrench. I used my newer wrench (Craftsman 5-250 in/lb) to torque the bolt to 240 in/lbs ( 20 ft/lbs). I'll let you know if it leaks.
This PML cover holds more oil than I calculated. Stock capacity is 4.75 pints (~2.5 qt.). Pml claims their cover increases capacity by .8-1.0 qt.. Well I have poured 4 qt.(8 pt.) of M1 75w90 syn into it and its not up to the level-check-hole yet. The truck is level. The check hole is too small for my finger. Will have to add more oil til it comes out the hole. I'm not upset by this, just puzzled. If you do this install buy a couple of extra Qts of oil. It'l save a few trips to the store.

THere is that much of a difference between what you expect to put in based upon their increase in pumpkin size? Wow, no leaks by just sitting on your driveway?

No leaks so far. Did not need to add another qt. When I checked the level this AM it ran out the hole. Maybe I just needed to let that thick gear oil settle.
