Upper Header Seal, Inner, 76-91 Blazer

Upper Header Seal, Inner, 76-91 Blazer. The inner header weatherstrip is installed between the removable top shell and the steel roof of the truck (mounts to back of steel roof), under 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.
