Global Accessories 911 Weld-On Subframe Connectors 1967-73 Mustang Coupe Fastback

The Global Accessories 911 subframe connectors are engineered to significantly increase chassis rigidity and reduce body flex on 1967-1973 Ford Mustang coupe and fastback models, as well as 1967-1970 Mercury Cougar non-convertible applications. These weld-in connectors tie the front and rear frame rails together, creating a solid foundation that enhances handling, reduces rattles, and prevents structural fatigue.

Key Features:

• Constructed from 2-inch diameter round roll cage tubing with .125-inch wall thickness for optimal strength-to-weight ratio
• Round tube design resists torsional twist better than square tube alternatives while maintaining lighter weight
• Black powder-coated finish for corrosion protection and professional appearance
• Includes 3/16-inch structural mounting plates and additional gussets for reinforcement
• Tucks up tight to the floor pan for maximum ground clearance without floor modifications
• Sold as a pair with complete installation instructions

Installation Notes:

Professional welding is required for proper installation. These subframe connectors must be welded—not bolted—to ensure adequate resistance to chassis flex. Bolt-on installation will not provide sufficient material at the attachment points and can lead to the connectors working loose over time. The connectors attach to the factory support rails located directly under the front seats, with the rear portion connecting to the rear leaf spring mount and frame rail.

Applications:

These subframe connectors are essential for any performance application, including street driving, road racing, and drag racing. They are particularly important when running a roll bar or roll cage, and highly recommended for vehicles with high-torque engines to prevent sheet metal tearing and floor pan stress.

Important: This part number (911) is designed for non-convertible models only. Convertible Mustangs require part number 911C.
