If you don't have any experience doing this I wouldn't recommend it but I've done it countless times. If it's relatively flush or even in a little bit you can use a nut about the same size or a little bit smaller. Put the rod thru the nut holding onto it with a vice grip, glove and pull the trigger. If you do it right you 'll get a bite on the stud and the nut will stick. Hopefully heat will help it spin out once you put a wrench on it.
