These rubber mounts are located on the four corners of the chassis and keep it suspended giving the chassis some "wiggle room" to prevent the tubes from being jarred by someone bumping the radio. These new corners mounts will bring your chassis back up to the correct height and your control shafts will then be centered in the cabinet holes instead of rubbing on the bottoms of the holes.
