Yup, the top part of the mount completely broke off the bottom plate part. I removed the bolt from the front side before taking the picture. I had to drive the car 60 miles like that with a big (BIG!!) zip tie holding it together. Thank god for zip ties. =)
Pushing it hard on back roads... hard enough that I would have to keep it floored to keep the rear end from coming out on corners, but keeping in my lane.
