You can make a spool out of the standard front diff.

1. Do not install diff balls
2. Assemble the diff as per instructions (except diff balls and grease on pulley)
3. Use Dremel sanding discs - mark out the size first, the outside diameter is correct, you just have to mark and cut out the inside diameter (making sure that the smooth side is facing the diff plates)
4. Tighten up diff fully
** Optional only: make sure outdrives are lined up with each other - use slots. The reason for this is that you can see how much your spool has moved after a crash, and readjust (retighten) if required.
I have run a spool like this since the car came out and have had no issues (ie. breakages or spool letting go).
Just a note to all that are having issues with diff meltdowns:
the standard diffs work perfectly fine with low wind b/l motors (3.5t and 4.5t) as long as you take care when building the diffs.
1. make sure the diff plates are cleaned with motor spray
2. place 4 small blobs (equally spaced) of silicone grease on the outdrive - d-ring area
3. make sure the diff plate is facing the correct way (sharp edge towards the outdrive -facing down away from the pulley)
4. build diff as per instructions (diff spring precompressed/diff nut securely held in place)
5. make sure the diff is tightened properly

Unless there is a problem with your belt(s), you should not have to replace them anytime soon. I think one of the AE team guys posted earlier that they have been running the same belt since they got the car (about 9 months) and mine is like brand new (no signs of wear) and I have been extensively testing and racing the car for over 8 weeks now (3.5 and 4.5t b/l).
The Alum. diffs are not available yet. It shouldn't be long.
Hope this helps you guys out.
