I could not get the photobucket image to open so I could not see exactly what type of trim it has. If we can see a better quality image, we may be able to point you in the right direction.
BTW, pretty cool that you have been a 'lurker' for 2 years and are just now posting.
It appears what is on your car is "Landau Trim" used on Landau top cars of yesteryear. If that is what it is, it is quite hard to hard to find these days. Not sure any trim clips are available.
