The 1964-1970 Ford Mustang Left Rear Frame Rail is a heavy-duty replacement panel designed to restore the driver-side rear structural support of your classic Mustang. Precision-formed from high-quality, heavy-gauge steel, this frame rail replicates original factory dimensions to ensure a strong, accurate fit. It provides essential reinforcement for the rear undercarriage and is a critical component when addressing severe rust, collision damage, or a full frame-off restoration. This panel ensures your Mustang’s strength, safety, and structural integrity are fully restored from the ground up.
Installation:
Difficulty: 5/5 – Requires advanced welding, measuring, and chassis alignment skills.
Instructions: Safely elevate and support the vehicle. Remove the damaged rear frame rail by drilling out spot welds and cutting along factory seams. Prep surrounding metal and test fit the new rail for alignment with suspension points, trunk floor, and rear crossmember. Weld securely into place using factory weld points, ensuring structural alignment. Grind welds smooth, apply seam sealer, and coat with primer and paint before reinstalling suspension or body components.
