Goodmark GMK403379070 Rear Cross Rail Non-Wagon Steel Replacement

The Goodmark GMK403379070 is a replacement rear cross rail engineered for classic Chevrolet Chevelle restoration and repair projects (excludes Wagon body style). This structural sheet metal component spans the rear underbody, connecting the rear frame rails and providing critical support for the trunk floor, rear body panels, and suspension mounting points.

Manufactured from high-quality stamped steel, this cross rail is designed to restore factory-correct structure to vehicles suffering from rust, collision damage, or metal fatigue. It replicates the original OEM profile and mounting locations, making it a proper foundation for a quality restoration.

Key Features:

• Factory-correct stamped steel construction for OEM-matching fit and strength
• EDP (Electro-Deposit Primer) coating provides corrosion resistance prior to final finishing
• Replaces the original rear cross rail / rear crossmember in non-wagon body styles
• Designed to restore structural integrity to the rear underbody
• Compatible with standard coupe and hardtop body configurations — not for Wagon applications
• Test fitting before final prep and paint is recommended for best results

As with all Goodmark sheet metal, minor imperfections such as small dings or primer scratches are considered normal and are easily addressed during the standard filling, priming, and sanding process. Professional installation by an experienced body technician is recommended to ensure proper fit and finish on your restoration build.
