Arrays of non-rod shaped optical elements may be integrated with fiber arrays arranged in a positioning structure. The assembly includes a carrier and a brush selectively adjustably moveable with respect to the carrier. The system is defined as including a hydraulic circuit connecting the battery to a tank. In use, the retaining fingers grasp a first connecting member on the trim cover and move the first connecting member toward the working surface as the actuators are moved toward the working surface so as to engage the first connecting member with a second connecting member in the foam pad thereby securing the trim cover to the foam pad.
