Took the car for a drive yesterday and had one of the differential mounting point fail during a quick acceleration from stop. The mount on the front of the differential close to the driveshaft connection pulled apart and let the driveshaft move up and bash part of the chassis. No major damage but have to put in a new mount that can take both tension and compression forces. Installed mount followed the Saturn Sports Car guide recommendation, but the component was not designed to take any tension so pulled the rubber apart. Photos below.
