I've had a look and non genuine arches and rub strips (full set 63mm width) would be £170 (4 arches with short trims, 2 door strips and 2 rear qtr strips and all mounting parts). These would come from Germany and take approx 5-10 days.
Genuine are available but they are just under £330 for the same parts (and would need specially ordering from Germany and can take 3-4 weeks!)
Not cheap and finding them was good fun!
