Thank you to all of you who gave me an answer and simply understood what I was talking about. It is supposed to rain tomorrow anyway, so I'll just get it fixed up right after work on Monday and be done with it and not really lose any riding time.
Suggestion, ask the bike shop for a couple of spares, put them in a 35mm plastic film can, with a label and stick that in your tool box. In the future, if you ever need to change out a cable, you already have the end to crimp on.
