I broke it
 

I broke one of the fasteners that hold the door panel on. Its one of the ones that you pull the center out and then remove the fastner.

Is there a part number for this so I can get a replacement?

How did I break it you ask. I removed it and then set it on the garage floor. 5 minutes later I take a step and hear a crunching noise. I can't believe that I stepped on the thing.
