This pivot block for the Nikko Bison/F10 will replace the broken one on your car. This version will allow you to not need to reinstall the press fit collar on the pivot shaft and will allow the shaft to fit within the pivot block. Make sure all holes are cleaned out including the main bore for the pivot axle. This has only been tested on two of these cars so there is a possibility that some minor alterations may be needed for your car.
If you want the stock pivot block, it is part number F10001-02
