A vibration isolator device securing a nonmetal panel to a metal frame of a work vehicle includes a metal member affixed to a surface of the nonmetal panel, the metal member facing the metal frame. An isolator mount plate is secured to the frame in a manner permitting a predetermined adjustment between the isolator mount plate and the frame in each of two directions. A vibration isolator is positioned between the metal member and the frame. A region of the isolator mount plate is configured to receive and maintain vibration isolation between the region of the isolator mount plate and the metal member, the region of the isolator mount plate providing a predetermined adjustment between the isolator mount plate and the metal member in a third direction.
