To get accurate dimensions, you need to specify the *exact* model of your '82 Dodge truck. Then you can find specifications (length, width, height, bed length) in sources like:
* Owner's manual: If you still have the original manual, it will have the exact dimensions.
* Online resources: Websites like classic car parts suppliers or Dodge truck enthusiast forums might have specifications based on the model. Try searching using the full model designation (e.g., "1982 Dodge D150 short bed dimensions").
* Repair manuals: These often include detailed dimensions.
Without knowing the precise model, I cannot provide the dimensions.
