Looking for a blank interior button

I am under the impression that some espec Mx6's came with a blank dummy button next to where the headlight adjustment switch is. Would anyone happen to have an extra one around? I just removed the cruise control from my car and I'd like a blank button to replace my cruise one with.

I'm in the USA so hopefully it won't cost much to ship something so small.

Here's a picture of what I am looking for.



Thanks!
Chris
