If you can't contact anyone see if you can just get youself some .060" fiber optic. All you do to install cut a piece about 1/4" or so longer than you need and heat one end and put a small 'button' on it. slide it through the brackets then snip off excess leaving about 1/16" protruding. Heat that end and whlle holding the opposite end in, put a 'button' on that end. Be careful not to overheat the fiber or it will blacken.
