This is a part for the Oversized Feral Rex foot. There's a tab in the base of the foot that lines up with a tab in this bracket that helps keep the feet solidly aligned. Due to the offset nature of this tab, it works better for one foot than it does for the other. At first, I thought I had two of the same foot, so I requested a replacement pair. The replacement pair was also the same, now leading me to believe that the tabs are all the same on the feet. To counter that, I designed this replacement bracket for OS Feral Rex's foot. This mirrors the existing bracket, and will work as-is. Some minor work with a screwdriver will be required to replace the foot.
