To find the GVWR for a specific 1983 GMC Vandura, you need to:
* Locate the Vehicle Identification Number (VIN): This is usually found on the driver's side dashboard.
* Use the VIN to look up the specifications: You can try using online VIN decoders (many are available, but check their reliability), or contacting a GMC dealership or parts supplier with the VIN. They may be able to access the original specifications for that particular vehicle.
* Check the vehicle's documentation: The owner's manual or any other paperwork that came with the van might list the GVWR. Look for a sticker on a doorjamb or the glove box as well; this sticker often contains weight information.
Without the specific model and configuration of your 1983 GMC Vandura, it's impossible to give you a precise GVWR.
