Backlash Post Measurement, got lucky like most people, backlash only changed ~.0005" (from .004 to .0035, not going to mess with it)
Gear Marking Grease - looks good to me. Went forward - took picture, then backwards took picture (driving by hand on front shaft)

Installing the stub-shafts - My OS Giken came with the spring clips already inside the LSD. I needed to remove them from the stub shafts prior to install. Put the differential on it's side and center the clip in it's cavity prior to installing the stub shaft. I will allow it to snap in easily.
Install Cover - Make sure you clean it before putting it on. My cover had a bunch of aluminum shavings in it...nice.\
Permatex grey came with kit, clean surfaces and follow directions. (use alcohol, lacquer thinner (my favorite) or acetone for final wipe)
Install Rear stud (used blue Loctite) and fill with gear oil
Rear bushing gets installed from the front, lube it up first. Then press in hub. Push it in about 1/2" extra
Differential is a PITA, the front has to be raised fully into position for it to slide back far enough to get the bolts in. The jack alone won't do it due to the position it's pushing up at. I needed to block it up with wood to get one side high enough. Took me forever to figure out exactly what the problem was.
