This should be a simple question, at least I hope it is.

I had a tire that I was occasionally having to add air to get worse, to the point of losing 22 psi overnight. This morning I go to take the tire off and see if I have something in it that I can plug for the time being. Getting the tire off was a complete issue in itself. F^CK whoever put this back on last, and F^CK GM for their cheap ass capped lugnuts.

So anyway 45 minutes of fighting later I finally got the wheel off. I go to put air back in so I can start searching for a hole, only to find that that valve stem is broken. Its the actual threaded part that that cap would screw to that is broken, the stem itself is in one peice and would probably hold air, but I need to get this fixed. I was looking on RockAuto and a few other places and this is where I need your help. Its hard to tell by the descriptions, but do the TPMS rebuild kits come with that part, or am I going to have to bite the bullet and get a whole new TPMS unit?

Thanks in advance.
