Abstract: A tailgate gap cover releasably engages a vehicle body having a gap disposed between a back end and tailgate of the vehicle body. The tailgate gap cover includes a plate that extends between a plate leading edge and a plate trailing edge and a flap that extends between a flap leading edge and a flap trailing edge. The flap leading edge is pivotally connected to the plate trailing edge to allow rotation of the flap relative to the plate between an open substantially parallel position and a closed substantially perpendicular position. A fastener releasably secures the plate to the vehicle body. The fastener includes a base that is secured to the plate and a latch plate that is secured to the vehicle body and is moveable between a locked position for securing the tailgate gap cover to the vehicle body and an unlocked position for removing the tailgate gap cover.
