ES do not have them anymore, I also tried the local dealer in the NL. I will first try to source a new one, if really not available, I will repair my existing case.
It doesn’t take paint very well either - removed and cleaned on cam belt replacement , a few months later removed again, paint had flaked despite being wire brushed and primed. I had to do it again and looks okay now, but I did have issues with the paint bubbling
