1958 Chevy Impala Hardtop/Convertible LEFT Vent Window Assemblies NOS

These original 1958 Chevrolet Hardtop or Convertible LEFT/DRIVER'S SIDE vent window assemblies an NOS part #4715337.  The piece is in good driver condition.  The rubber may need to be changed since it has sat for so many years but it may still be good. There are some minor imperfections (see images).  For instance, the inside portion looks like part of the chrome had been grooved somehow.  Not show quality but good driver.
