We’re here with a passenger 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 commonly rusted out part in your 1965 through 1970 Mustang. This piece is going to extend from the front of your floor pan, up to your firewall. If you happen to have a leaking cowl, many times the bottom panel will get rusted out. This will fit '65 through '70. Will require modifications though for a 1967 through 1970, or, any 1965 through 1966 that had a torque box added. When installing this on a vehicle with torque boxes, you're just cutting out the floor to firewall extension around the torque box so you don't have metal stacked on metal. It shouldn't cause condensation or rust in the future. Matching driver side is also available.
