We’re here with a driver side floor to firewall extension fitting your 1965 through 1970 Mustang. The floor to firewall extension is also known as the toe-board and is a very commonly rusted out part on your 1965 through 1970 Mustang. This piece is going to go from the front of your floor pan and extend up to your firewall. If you have a leaky cowl many times the bottom edges will get rotted out. This will fit 1965 through 1970 Mustangs. It will require some modifications for 1967 through 1970 or any 1965 through 1966 that has had a torque box added to it. When installed on a car with torque boxes we do recommend cutting out the toe-board around the torque box so you don't have metal on metal which can cause condensation and rust in the future. Matching passenger side is also available.
