I just file the top half of the head off of a standard backup spoke and then slide it in to the hub hole. Basically, if the threaded end is at the twelve oclock position with the head on the right side forming an "L", you file the top 1/3 to 1/2 of the head off (leaving the bottom portion so it looks sort of like a "Z"), then it will work fine. Have used this technique for the past 25 years and it holds up fine. Best to replace when you can though.
