A mounting platform includes a slide having a mounting shoe thereon with the slide being mounted to the platform for movement between at least first and second spaced-apart positions. In a preferred embodiment, the platform includes a guide for the slide which is spring-loaded and which slides within the guide and includes interlocking tabs and slots for positively locking the slide in at least two spaced-apart positions, thereby longitudinally moving the mounting shoe between such positions. In a preferred embodiment also, in order to provide a finished appearance to the mounting system, the slide includes a forward section which extends through an aperture formed in the platform and slides along an upper surface thereof with the body of the slide extending through the aperture into the guide such that the aperture remains enclosed by the main body or forward extension for all positions of the slide, thereby enclosing the platform.
