A tailgate sealing arrangement for sport utility and other vehicles having a removable, flexible top. The sealing arrangement includes an elongated, rigid member attached to the lower section of the rear portion of the flexible top. The rigid member is removably mounted to extend across the tailgate opening and has a flexible seal depending downwardly from it. The tailgate in the preferred embodiment is mounted for pivotal movement about a vertical axis and has a horizontally extending, flat, upper surface. In operation and as the tailgate is closed, the depending seal contacts and wipes across the flat, upper surface of the tailgate to form an effective sealing arrangement. All of this is done without having to disturb or otherwise manipulate the top.
