Someone dumped a Ram 3500 on my property. No plates, and the cab and part of the engine compartment are burned. It has a steel flatbed and probably was a weldor's truck. It hs a V10 engine and a transfer case putting the front driveshaft under the driver. It has a Dana 80 rear with 4.10 gears. Dual tires. Regular cab.

The VIN plate was destroyed and there is nothing left in the cab or under the hood that easily identifies the truck. The door and jamb are bare except for some ashes.

Where would I find a VIN on this hulk? Any other way to identify? There is a tag on the rear end with a part number. Would this help?
Thanks!!!
