Our CK trunk floor includes the stiffener rib. Trunk floor corner supports are spot welded into place. The panel is made in two pieces to more easily facilitate frame-on installation. (The center joiner strip will conceal the joint which is slightly to the left of center.) Note also that the black lines shown on the panel indicate areas to be trimmed off if not needed or cut & rolled up if needed.
Please call if you have any questions, 715-234-4677.
