I am almost positive that the AE center shaft is too long to fit. However, I remember seeing someone post a picture of a customized, shortened one he used on the SD.
I just got back from the ROAR regionals, at the same track as the Nationals this year (Rose City), and as far as setup goes, I would HIGHLY recommend using a spool on that track. I was struggling with my car's handling all weekend, I really wanted to get the one-way to work, but traction was too low (I think) and I eventually gave up on it and put in a spool. The car was much faster and easier to drive after dialing in more off-throttle steering
To build a spool, just use an old diff and CA glue sandpaper to the diff rings. The sandpaper must be cut in circles the same size as the rings, and have holes reamed in them to let the diff bolt through. Then just build the diff as normal, but w/o diff balls. Tighten it all the way, and back off a little to let the spool slip in case of an accident (maybe a half turn).
It might be easier to buy a steel spool, but this one saves weight and is less expensive (but more fragile
