Headrest gasket/plastic part number?

[02_SE_Runner]

After about 30 minutes googling "02 4runner headrest (BLAAAH) I could not find it out. So.... (Pic attached I know blah blah I spelt piece wrong lol).
What is this piece right here, and do you know the part number for it? Have you ever broke one at some point? Somehow I broke one :dammit:, and hate having the headrest rattle everytime I hit a bump. :ybrick:
Thanks for your help.

I think I found the part here:
2002 TOYOTA 4RUNNER Parts - Conicelli Parts Center
Is it number 15? Is it left or right? (I have the grey interior which do I order? Oak or Charcoal?)
Thanks.
