Front Door Vent Window Set

This four-piece front door vent window weatherstrip set fits 1933 Buick Series 50, 60, 80, and 90 models, including coupes and sedans. Molded left and right, these seals replicate original parts for a precise factory fit, ensuring your vent windows seal tightly against wind and water.

Made from durable top-quality rubber, this set includes main vent window seals and division post seals. The division post seal (part #70-0040-56) is a 30-inch extruded rubber strip that you may need to glue onto your original post core or directly to the post.

Installation is straightforward: the seals fit right into the vent window frame, replacing factory parts #4034771, #4034772, #4042822, and #4042823. For best results, measure your originals to confirm proper length (these measure 35-1/2"; alternate lengths available).
