Hi Sam
Welcome to the Forum
Try looking at www.realoem.com put the last 7 digits of your Vin into the search box then check out the relevant sections if the black trims are available, you should have no problem finding them.
If they aren't there, then I would try a Body Shop or the aftermarket suppliers. Wheels same thing get the style and part number then I would check the Specialist dismantlers
Good Luck
Dave
