I broke this cable guide in a bike stand and wondering how bad the fix for it is. I would like to preserve the original paint. Is it possible to use one of those micro torches and heat the broken one to remove it then either braze a new one on in the same manner without damaging the paint (except on the guide of course, I have a touch up paint that is close in color to paint the guide) or could the new one be JB Welded into place?

Where can I buy a single matching cable guide?
