Upper Header Seal, Inner, 73-75 Blazer

Upper Header Seal, Inner, 73-75 Blazer. The inner header weatherstrip is installed above the windshield of the truck, closest to rear of truck (plugs into top of door rubbers), seals the front edge of the top. The Blazers were unique because the header seal is made up of two separate pieces, the inner and outer. This header seal will replace the factory installed weatherstrip perfectly.
