To find the exact dimensions, you'll need to:
* Specify the year and model of your Silverado: (e.g., 2023 Silverado 1500 Crew Cab)
* Consult your owner's manual: This is the most reliable source.
* Check a parts website: Websites selling replacement glass (like AutoZone, Advance Auto Parts, or specialized truck parts sites) often list dimensions for specific years and models.
* Measure it yourself: This is the most accurate way if you have access to the truck.
Without this specific information, I cannot provide the dimensions.
