Nice guide Damon. Says most of the important points, simply.
The punto box part should be expanded, as you suggest, when there is better info on it. Myself and Arran are finding out that there are more than a couple of custom parts required in reality. I would still recommend anyone doing this project on a whim or for a bit of fun to use the standard Panda box. The chances of you breaking the box are very small unless it is already on the way out or you tune the motor significantly. It isn't built with any more gusto than the Punto box in reality. A friend has re-built both style boxes completely and upon inspection the shafts and bearings aren't any better duty in the punto boxes. This is my opinion anyhow.
