To determine where to mount the second tonneau cover's hinge/driprail, Rob measured the length and width of both covers, in addition to the length and width of the bed. He wrote the measurements on the underside of the covers. |  He used the carpenter's square...  He used the carpenter's square to locate the second hinge/driprail and marked the location on the bedsides. Since the holes would show through the bedsides, nutserts can't be used for installing the second tonneau's hinge/ driprail... |  ...Rob also measured where...  ...Rob also measured where to position an angle iron bracket and figured out how big it should be. |

Rob bent each sheetmetal piece to form 90-degree angled brackets. |  For mock-up purposes, spot-welds...  For mock-up purposes, spot-welds attached the brackets to the bedsides. |

The power actuators will not be installed until later in the pickup's build. Installing the covers took Rob a bit over three hours, not bad for the first installation of the one-off Pro's Pick twin tonneau covers. |  Open or closed, the covers...  Open or closed, the covers look great. Stay tuned for the next article on the F-100 Super-Nationals giveaway truck. Until then, case(s) closed. |
