I am hoping to do mine without removing the sub frame as well. I will order those 2 parts. I could order the Urethane, too, and see what the guys think that are helping me with this project. I don't know anything about the structure of motor mounts. That photo helps me understand the urethane thing better, though. My mechanic said my mounts had collapsed -- so does that mean where your urethane is, mine will be empty? Or that I can clean it up and put the urethane in?
