If you go to the On30 Kitbashing or Conspiracy forums, look in my Spring Creek Models photo folder. I have run some castings for a On30 diesel body that is dased on a GE Export prototype but slightly modified. It will fit on either HO chassis, S scale chassis, or it will use the NWSL power trucks. I have sideframes that measure out to a 6 foot wheel base that will fit these. These are resin castings and have basic details and are easily modified for any kit bashing project. I plan to offer thses on an order filled basis. Priced VERY reasonable. Send me an email if interested. [email protected]
