Hey Casey,
This is the gasket, it seals the outside of each headlight assembly against the car body. I haven't removed them, but it feels very tacky and ready to fall apart - I'd like to have new ones on hand, so I can pop off the lens, recondition all the plastic, at the same time as re-bulbing it; without fear of having the gasket disintegrate.
While I have someone's attention, is there part numbers for these round screw nut clips that hold down the liner in the frunk, as seen here?
And even further questions: does Pelican carry the third brake light housing (I can find the clip for the third brake light, but not the whole thing itself - my whole third brake light is functional, but it's kinda "meh" and I've seen them for around $100, but not on Pelican). Also, do we have the roof rack clip parts (I think: 99655972900, 99655940501, and 99655940301) to fix them up so they don't look all collapsed as the plastic fails?
