The 1970-1973 Camaro / Firebird Rear End Cross Rail is a critical structural component that supports the rear body, trunk floor, and bumper assembly. Located at the back edge of the trunk pan, this heavy-gauge stamped steel rail ties together the quarter panels and rear valance while providing a mounting point for the rear bumper brackets. Commonly affected by rust and damage, this panel is essential for ensuring proper rear body alignment and structural integrity. Engineered to factory specifications, it delivers a precise fit and strong foundation for full rear-end restorations.
Installation:
Difficulty: 5/5 – Requires welding and precise panel alignment.
Instructions: Remove the rear valance, trunk floor edge, and any remaining original cross rail material. Clean and prep all mating surfaces. Test fit the new cross rail to ensure alignment with quarter panels, bumper brackets, and trunk structure. Weld securely into place, grind smooth, and apply seam sealer and protective coatings before reassembling surrounding panels.
