Rear door vent weatherstrip

This rear door vent weatherstrip is a fully molded rubber seal designed to fit 1951-1953 Buick and Oldsmobile 4-door sedans. It replaces factory part numbers 4180968 and 4180969, providing a reliable seal around the vent window to keep out water and wind noise.

Note that this weatherstrip does not include the division bar seal. For that, you'll need to order part #70-0040-56 separately, as we currently don’t have a matching metal core division post seal included.

Installation is straightforward—remove the old weatherstrip carefully, clean the channel, then press this new molded rubber seal into place ensuring a snug fit around the vent window frame. This helps maintain a proper seal and protects the interior from the elements.

• Fully molded rubber main seal
• Replaces factory #4180968, 4180969
