The bushing attach into a tube in the engine mount.  I took the engine mount off to do this work. The bottom bushing fit very well after removing a little powder coat from the inside of the tube. The top one was a different story. The tube has an asymmetrical truss support at the top and when I tried to fit the top one, I could see that the stresses from welding had taken it just slightly out of round. After a lot of handwork I got it to fit. I then did a trial fitting of the parts.
