Generally speaking:
* 1999-2005 Ford Excursions: These years share the most body parts. The differences are usually minor trim variations. You'll have the best luck finding interchangeable parts within this range.
* Other Ford Super Duty Trucks (F-250/F-350): Some body parts *might* interchange, particularly those related to the chassis and undercarriage. However, significant differences in body styling and dimensions will likely prevent many direct swaps. Careful comparison is essential.
Before attempting any part swap:
* Verify Part Numbers: Always compare the part numbers from your 2000 Excursion to the part you're considering from another year. This is the most reliable way to ensure compatibility.
* Visual Inspection: Even if part numbers seem close, visually inspect the parts for dimensional differences.
* Consider Trim Level: Different trim levels (XL, XLT, Limited) might have unique body parts.
In short, while 1999-2005 Excursions are your best bet, you need to research specific parts and verify compatibility before purchasing. Using online parts catalogs that specify the year and model is crucial.
