Sherman 580-20L Front Driver Side Inner Door Bottom Panel Ford Super Duty / Excursion

The Sherman 580-20L is a replacement left-hand (driver side) front inner door bottom panel engineered for Ford Super Duty trucks (1999–2007) and Ford Excursion (2000–2005). This stamped steel repair panel addresses one of the most common rust and collision damage areas on these heavy-duty vehicles — the lower inner door structure — restoring both the structural integrity and appearance of the door.

Sherman has been manufacturing quality replacement auto body parts since 1981, and the 580-20L is built to OE specifications, ensuring a proper fit without the need for cutting, grinding, or modification beyond standard body repair techniques. The panel is designed to weld into place using factory-style fitment, making it a preferred choice for body shops and DIY restorers alike.

Key Features:

• OE-style stamped steel construction — matches original gauge and contour
• Driver side (left-hand) front door application — direct replacement for rusted or damaged inner door bottoms
• Precision stamped fitment — crisp body lines designed to align with factory door structure
• Limited lifetime warranty against defects in materials and workmanship, including perforation due to corrosion under normal use
• Compatible with Regular Cab, Super Cab, and Crew Cab configurations (front door)
• Manufactured by experienced automotive stampers — many of whom also supply OEM parts
