Door Weatherstrip

This door weatherstrip set fits the bottom and corners of your vintage Chevrolet, Oldsmobile, or Pontiac doors from 1949 through 1952. Molded for right and left sides, each strip measures 40-3/4 inches overall length to ensure a proper factory-style fit. These weatherstrips replace original factory parts #4578148 and #4578149, helping to seal out water, wind, and noise for a quieter, drier ride.

Installation is straightforward: remove your old weatherstrip, clean the channel thoroughly, then press the new molded weatherstrip into place, making sure corners align snugly. This helps maintain your classic car’s original comfort and protection.
