J.C. Whitney JD58140020 Cab Corner Panel Left Inner Extended Cab Replacement

The J.C. Whitney JD58140020 is a direct OEM-replacement cab corner panel designed for the left-hand (driver side) inner position on Dodge full-size pickup trucks with Extended Cab (Quad Cab) configurations from model years 1998–2000. Cab corner panels are among the most rust-prone areas on aging trucks, and replacing them with a properly formed panel restores structural integrity and the clean appearance of the cab's lower rear section.

Key Features:

• Direct OEM Replacement: Engineered to match the factory panel's contours and mounting points for a precise, accurate fit
• Left-Hand (Driver Side) Inner Panel: Designed specifically for the inner cab corner on the left/driver side of the vehicle
• Extended Cab / Quad Cab Fitment: Correctly shaped for Dodge full-size pickup Extended Cab and Quad Cab body styles — not interchangeable with standard cab variants
• 1.2mm Steel Construction: Heavy-gauge stamped steel provides durability and resistance comparable to the original factory panel
• Weld-In Design: Intended for professional or experienced DIY installation using standard MIG welding equipment
• Restores Structural Integrity: Replaces rusted, damaged, or rotted cab corner sections to return the truck body to proper form and function

This cab corner replacement panel is an essential part for collision repair, rust repair, or restoration work on 1998–2000 Dodge full-size pickup trucks. As a direct-fit piece, it minimizes trimming and fitment adjustments during installation.
