They sent me three zipper sliders with the pull attached. I threaded the new slider on from the top and then broke the old one off. Good as new for the time being.
But honestly, had I been aware of the suggestions that were made in this thread, I'd likely have just gone that route without bothering to contact them. Good to know, however, that they did take care of my issue.
Thanks for the comments.
