Features and Benefits:
- Direct-Fit Replacement
- Premium Gauge Stamped Steel
- High-End Black Primer Coating

This is a complete firewall panel, which includes the entire vertical panel up to the cowl and the two toe board panels that attaches to the floor boards. This full assembly is crafted from heavy gauge stamped steel and will arrive with a black primer coating for protection during storage and shipping.

Please Note: The mounting holes for the Parking Brake Handle Assembly are incorrect. Slight modification is required.

An original 1965-1966 Coupe and Fastback firewall had a flange on the sides where it meets the A pillar. Our replacement firewalls do not have this flange so you will be required to fabricate it. However, installing torque boxes (recommended) will fill the gap and you can simply seam seal the space instead of fabricating a flange.

Vehicle Fitment Note: Requires modifications to fit Convertibles.

Whether you’re looking for an exterior mirror, wheels and tires, headlights and taillights or a set of interior upholstery, CJ’s has the parts you need to complete your classic Mustang restoration with ease!
