Shawn (Same one on this thread) places the fill hole up high, well above the factory location. This little adjustment immediately allows you to run more fluid!

NOSSIR! I have run one of his rear covers on my AAM 11.5 diff in my LML Duramax truck overfilled by half a gallon for a year now with nary a single spot of a leak!
His stuff works!
