Wiper problem

[ssmoparviii]

So its been a while since Ive posted but now I need some help. On my 2006 LS I was in the process of removing the degas bottle and when I went to remove the nut that held the driver side wiper arm on not only did the nut come off but part of the stud came off also.

So my question is can you replace just the stud or do you need to replace the whole thing?

Any input on this would be great so I can get the LS back on the road.

I'd get the whole assembly from a junkyard and swap it out. (2003 to 2006 will fit)
