Here is the trans after the rebuild. Rebuilt using LOSI 3078 Diff Hardware Set, LOSI 6951 Carbide Diff Balls and LOSI Diff Grease. I went with a LOSI 88T 48P Kevlar Spur dual slipper gear, but I may have to swap in the stock BK 84T if the 88T rubs on the RPM gear cover after final fitting:
Here is the rear end before dropping in the trans and motor plate:
In this picture you will see that I had to move the rear hub carriers in "one hole" on the rear arms. For some reason, the graphite rear arms (same part # as stock) have one extra set of holes to the outside as compared to the stock BK arms. Leaving the hub carrier in the "outside holes" ended up with the rear axles / dogbones being too short to reach the outdrive cups of the diff.
And now that the hub carriers were moved in one hole, the part of the rear arms that extend past the hub carrier hit the inside of the rear wheels. Other than cutting off the extra set of holes on the rear arms, any suggestions to work around this issue? I would rather not take apart the rear to install the stock KW arms that are all scuffed up from use. I have to take a look at the recent thread detailing another member's BK CR build to see what those rear arms look like.

And with the electronics installed:
Next steps: Resolve rear arm issue, get the D5 motor installed, cycle the Sanyo 3300 pack a few times to hopefully get consistent charges to the pack, adjust diff, slipper and rod ends.
