Unfortunately for us, while the Sd.Kfz 10 was the "basis" for the Sd.Kfz 250, there were major changes made. Very little of the work done for one model could "port over" to be the start of the other model. The hull was shortened enough to drop a wheel, and the front end was also changed.
As they mentioned, they "might" get to reuse the two front wheels. And that is about it!
