2. You’ll need some kind of faceplate or bezel for the screens. OneGauge sells custom cut bezels like the one in this picture that are pre-cut to fit the screens you’ve purchased. This customer wanted one large 7″ center screen flanked by two 3.5″ screens on either side. We cut him a bezel out of 1/4″ ABS plastic.
The bezel then mounts to the back or base of the instrument cluster (white piece in the photos). However, the screens stick out from the bezel by about 3/8″ or so, and there was going to be some interference from the white base, so we marked the areas of the base that needed cut while trying to leave enough of it to retain its rigidity.
