Vent Window Division Post Weatherstrips

This Vent Window Division Post Weatherstrip pair fits the front doors of 1955-1957 Chevrolet and Pontiac models. Molded with a metal core and brass tabs, it seals the vent window when closed, preventing drafts and water leaks. Designed to replace factory parts #4156330 and #4156331, these weatherstrips are crafted from top-quality EPDM rubber for durability and a precise fit.

• Fully molded with metal core and corrosion-resistant brass inserts
• Seals vent window opposite the glass run channel
• Sold as a pair for driver (LH) and passenger (RH) doors
• Made in the USA and guaranteed to fit

For installation, remove the old weatherstrip and clean the post surface, then align and attach the new strip using original mounting tabs. Using a weatherstrip adhesive like 3M Super Weatherstrip Adhesive can improve hold. A scraper or tuck tool helps to seat the strip properly. Check your vehicle compatibility before ordering.
