Not sure about the Al diff cup, but a full 8th scale CD shouldn't be hard:

1) Drill two new mounting holes to allow room for the added length of the diff

2) Dremel out a cutout in the chassis for the spur, or raise the diff a couple mm.

3) Use different mounts, or mod the stock ones, since the stock CRT.5 CD bearings are an odd size (1mm smaller in diameter than typical 8th scale).

4) Mod the length of the dogbones or fab new ones up.

5) Out drive cups. I can see a couple options. A) Use 8th scale out drive cups on the F/R diffs if you can find ones the right post diameter B) Mod the stock bones so you can use them for the F/R diffs, but have the CD end use regular 8th scale size.
