To find the weight of a *specific* 1988 Chevy cargo van, you'd need to:
* Find the Vehicle Identification Number (VIN): This is crucial.
* Use the VIN to look up the specifications: You might be able to find this information through a Chevrolet dealer, a vehicle history report service (like Carfax or AutoCheck), or possibly online resources dedicated to classic vehicle information. The GVWR (Gross Vehicle Weight Rating) is particularly useful. The curb weight (weight of the vehicle without cargo or passengers) will likely be listed as well.
Without the VIN, providing a precise weight is impossible.
