Holy crap!! I just installed new urethane motor mounts that I got from AM and a new transmission mount that I got from the dealer and the car feels like it's new. The ones I had were so jacked up the rubber was basically torn in two on the engine mounts and the trans mount was almost in two pieces. After I had everything installed and got in I thought there was something wrong with the car because of how smooth it was at idle. I highly recommend this to anyone with a high mileage stang.
