The body is unitary, thin, substantially flat in a normal state, and flexible. Adhesive elements are disposed on the outer panels to fix the holder to the surface to be shimmed. Also disclosed is a shim holder including an outer member; an inner member for contact with a surface to be shimmed; and at least one elastomeric connecter for connecting the outer member to the inner member. An adhesive element is disposed on the inner member for fixing the inner member to the surface to be shimmed.
