Thinking to look original does not mean have to be so
So thinking outside the Box how about using Acrylic tubing.
Found these but must be others

you could either cut yourself or maybe the supplier could do it for you. Getting the original look is easy either use a palm sander or one of those spray paints you can use on clear glass. much easier to drill as well
What do you think
