These 1955-1956-1957 Chevrolet 4-Door Hardtop or Convertible right/ passenger's side vent window assemblies are a reproduction of the original. Note that the hardtop assembly is shorter than the sedan making the glass or stainless NOT interchangeable.
Are your vent assemblies leaking or the glass bubbling along the edges? These reproductions use all new parts including, rubbers, channels, and glass with chrome channel. They look great and are ready for installation.
