Ruben, I too was working on a car with fiber optics, and like you missing some line. I found about two feet at a Corvette shop in Portland, Oregon about 6 years ago and that was all they had, and I was still short but made due with what I had. I know the telecommunication industries have been using fiber optic cable for years. It's a long shot but might be worth calling one up and asking some questions. Also if your chrome parts are pitted have them rechromed, the after market ones are crap and they need a lot of modifying to make them usable with the original optic parts, sorry I could not be more help finding the cable.
