Need quick help with 8 3/4 rebuild kit!!

Update: Picked up the 3rd member last week, got it installed today. Backlash in the old gears was .007, backlash in the new gears is .008

Drove it around and not getting any whine on accel or decel. My guy did a pretty decent job. Happy with the 3.23 gearing and the eaton trutrac!
