To find the weight of a *specific* 1986 Ford van, you would need to:
* Find the Vehicle Identification Number (VIN): This number is unique to the van.
* Use the VIN to look up specifications: You might be able to find the weight information through a Ford dealer (though records from that long ago might be incomplete), online VIN decoders (though accuracy isn't guaranteed for older vehicles), or in owner's manuals if you have one.
Without the VIN or more specific model information, providing an accurate weight is impossible.
