From a local parts car and some serious removal attempts, this part isn't really removable. Hopefully this will help someone, took a while to track this part down.

How about a picture of the part and where it goes, I looked up the photo of the part and can guess where it goes, but it is only a guess. You may get a suggestion of something else that can be used in its place..
