Roof Rail Filler

This roof rail filler is a weatherstrip designed for the front door upper corner, outer section at the front end of the flipper on 1954-1956 Buick and Oldsmobile hardtop models. Molded specifically as left and right pieces, it features a corrosion-resistant brass metal core to ensure a long-lasting fit and protection against the elements.

It replaces factory part numbers 4657465 and 4657466, making it a reliable replacement for your vintage vehicle’s weather sealing needs.

Installation Tips: Carefully remove the old weatherstrip and clean the mounting surface before installing the new filler. The molded shape will help align it perfectly for a snug fit that keeps out water and wind.

Note: Check the Matching Vehicles tab to confirm fitment for your specific car.

Warning: For California residents, please be aware of Prop. 65 regulations.
