The 99-07 automatic transmission Superduty trucks have a hole in the firewall where the clutch hydraulics mount. On some of the early trucks Ford provided a plastic cover for this hole. The later trucks have a thin sticker over it. This can rip and allow water, dust, or wildlife into the cab. Also, if you run any aftermarket wiring through the hole, this sticker will rip and make an excessively large hole. We designed this to fix that problem. This .125" thick aluminum plug will cleanly cover that hole and give you a nice area for a grommet or bulkhead connector for aftermarket wiring.
