This weatherstrip channel (often called window run channel or window channel felt) runs along the rear edge of the door frame on your classic truck. These vehicles do not have an upper door frame, so the window run channel fits on the rear edge of the glass include the door, and roof rail seals are used where the door glass meets the removable top (available separately). This weatherstrip reduces drafts, wind noise, window rattle, and allows the roll-up side windows to operate more smoothly. Includes two window run channels with enough material for both front doors on the truck. The window run channel is often replaced along with the division run channel, and windowfelt (both available separately).
