To find compatible rear windows, you'll need to:
1. Identify your Ranger's body style: This is crucial. Regular cabs, extended cabs, and SuperCabs all have different rear window shapes and sizes.
2. Check your existing window: Look for a part number etched into the glass itself or on the window frame. This will be the most accurate way to find a direct replacement.
3. Use a parts website: Sites like AutoZone, Advance Auto Parts, Napa Auto Parts, or RockAuto allow you to search by vehicle year, make, model, and body style. They'll show you the correct window for your specific truck. You can also search by the part number found on your existing window.
Simply searching for "2004 Ford Ranger rear window" is likely to yield inaccurate results, because multiple options exist depending on the specifics of your truck.
