It's hard for me to tell with the blue. My first instinct is pinion a tad deep but if they are running good with no noise or anything I wouldn't worry about it.
Whats the gearing? On my 8.25 the locker was fine on stock 3.55 gears. When I did 4.56 gears I had to shave a tooth down a bit to make sure the cross shaft could come out.
