Vent division bar weatherstrip

This vent division bar weatherstrip is a front vent window division post seal designed for select 1957-1958 Buick and Oldsmobile models. It’s fully molded with a sturdy metal core and has attaching tabs for easy installation. This weatherstrip fits opposite the glass run channel and effectively seals the vent window when closed, helping to keep out wind and water.

It replaces factory parts #4233018 and #4233019. For best results, pair it with the front door vent weatherstrip, which serves as the main rubber seal around the vent.

• Fully molded with metal core for durability
• Includes attaching tabs for secure fit
• Seals vent window when closed to prevent drafts and leaks
• Replaces factory #4233018, 4233019
