Product Details
Description
This vent division bar weatherstrip fits the front vent window division post on 1973-1979 Chevrolet and GMC vans and pickups. It's fully molded with a sturdy metal core and comes with pre-drilled holes for easy installation. It seals the vent window tightly when closed, fitting opposite the glass run channel. This helps keep drafts, water, and noise out.
Installation is straightforward—remove the old strip and align this part with the pre-drilled holes on the vent post for a secure fit. For complete sealing, pair with the front door vent weatherstrip, which handles the main rubber seal.
