Let me preface this story by saying that I am a tard. That being said, I recently purchased a new rear MM for my MS3 and attempted to install it. After for hours of my initial try I came to the conclusion that it was not going to fit. I talked to someone at Medieval who told me that this is a common problem and to use a pry bar and make room for the mount. I did this and got it in okay though when I went to tighten the mount I could not get it tight. I tried for quite a while and no change. I then removed the mount and slid the bolt in by itself and it tightened okay. After this, I had completely given up on the medieval mount and decided to put the OEM mount in. This time the bolt pretty much tightened though not to the recommended torque spec. I took the car for a ride and there was some metal clatter under the car upon start up though everything else felt fine. Can anyone help. Should I take the car to Mazda? Thanks!
