Like the add says, this is a fiberglass panel that fits against the cab to effectively turn a Bronco into a pickup. It has a sliding rear window, and follows the original roofs contours. It was sold thru the aftermarket. It works on the same principal as a Jeep top. It slides down in place, and a metal plate screws to the floor, to seal off the interior. Will post pictures as soon as I can. Asking $250 plus shipping. Fits full size Broncos.
