Having blacked the hood & trunk badges on my SE Sport, I'm looking to replace the " SKODA OCTAVIA " letters witrh a black version, does anyone know where this can be bought, many thanks. 

Sure. Here: https://www.kopacek.com/skoda/octavia-iii/emblems//2?f=o:price-

Many thanks Ray Luxury Yacht.

Just purchased the letters and black mirror caps from a local autorized dealer in Slovenia. The price was the same as if I purchased from Kopacek, Skoda Parts etc.
