1969 1970 Mustang Firewall Heater Box Washer Set - Best on the Market - USA

These washers support the firewall mounting points for the heater core and air conditioning evaporator box assembly on 1969 and 1970 Ford Mustangs (and possibly other vehicles). This is a 100% accurate reproduction of the original Ford part that was made to Ford's original design specifications, from the material (Hot Rolled Low Carbon (HRLC) steel), to the dimensions (2.25" outside diameter, 0.31" inside diameter, and 0.060" thickness), and to the phosphate and oil finish. Two are required per vehicle, so your purchase here includes a complete set of two washers.

Please note that C9ZA-19C624-A is the engineering part number for this washer
