Inspiron 9300 Palm Rest/Mouse Assembly Part #

Okay, I've spent a week or two now looking for this part number. I have YET to be able to find it anywhere. I found the part on eBay but the seller wouldn't answer any questions. My 9300 is LONG since out of warranty and the damage is only superficial, but I would like to replace it.

 

Basically, the paint job was REALLY poor on this particular unit. The paint came off after one cleaning so now I have a horrid spot showing under my left palm. Does anyone know the part number for the assembly?  I don't need to send it to Dell to replace. I could take this thing apart and put it back together in my sleep. If I can't find a replacement for it I am going to have to strip it and repaint it myself (which I stink at).

 

Any help would be appreciated. Thanks in advance.
