Dang Grease Fittings!

[Alvin]

So I'm in the garage, putting the control arm shafts in the control arms, just got done wrestling with the first one for 1/2 an hour and decide to go ahead and put in the grease fitting. Working with the smallest ratchet I have I tighten it down when *pop* the thing broke off leaving the threads in the cap. Talk about frustration! Oh well, guess I'll be taking it apart again tomorrow, hopefully an easy out can get the thread end out without tearing up the threads in the cap! Any advice? Surely I can't be the only one to have ever done this!
