Looking for part # B7A 7062199-AP.  This is the extension of the metal shield that goes on the side of the front seat cushion.  This part is used on 1957-1959 cars with power seats.  it protects the motor and mechanism area of the front seat from damage by anyone putting their foot under the seat.  it is only on the left side of the seat.  1955 and 1956 cars had a similar part on both sides.  Any help in locating this part is greatly appreciated!! 

Thanks to everyone.  I found my part.  Now some paint a few screws and it will be good as new.
