Of all the components, the diff was the hardest to measure. Its heavy, there isn't a straight or square edge on it, etc. If I had to guess the parts which would need adjustment, the diff mounts were it.
It took a lot of fiddling, but I got the diff placed where I want it. I need to shim the PS diff mount about 3/16". I didn't include enough adjustment in the mount itself. Not a big deal though.

The rear mount is pretty good as far as placement. I needed to clearance one of the support webs on the diff casting. I also didn't make the bolt entry wide enough. A few other minor trims here and there as well.
The front DS mount is going to need some adjustment. Its bracket is .4" to far forward, and needs to come down about 0.3". Not sure if I will just order a fresh bracket, or spend some quality time with my saw and grinder.
The good news is the pinion angle is correct. Adjustment is from +7 to 0 deg, which should be enough to get shaft aligned. Clearance at the CV flanges is good as well. And! The rack fits! Not as far back as I like, but close enough!
