Are you sure that you are installing the correct one into that side? I remember that my GSR mounts were slightly different and couldn't easily be swappable from side to side.
First off, you have to make sure you are using the correct mounts (driver or passenger side). Second, each mount has two inserts (one peice to the inside and the other peice to the outside of the mount). Make sure the correct one goes to the inside and the other peice goes to the outside of the mount. That way you will have a full insert on eah side of the mount.
Did you get the other side of the mount on though?
