Pricing 2003 plastic roof rail and covers (not cross bars)

[U3425head]

I have a 2003 P5 and the plastic molding around the roof fails and the caps have cracked and broken. I still have the original cross bars, still sealed in box, from when I purchased the car. The parts I am looking for are just the plastic that covers the metal rack mounts, both the small caps and the long piece. Does anyone know if these parts are available and if so, how much? I may just remove the mounts all together, but I thought I would ask around first.

Thanks,
Brian
