That can save you some money if you ever need engine-related repairs. (The mechanic gets the same hourly labor rate to pull codes as he does to do repairs...)
For the bus part...all I can suggest is, maybe ask at the local school bus shop? They might have an extra one for an older bus they no longer have. (IIRC, the IH 3800-T444E ran 1995-2001 essentially unchanged.)
(Edit because I misread the body manufacturer as Thomas.)
