Thanks a lot for your quick replies!!
@ Xavier: at the moment only the lower (small) bushing is available in both colours.
@ personne: yes, I had seen both threads, but have not understood everything perfectly: Did I get it right that Nico has already asked Hawaii Surf about the red upper bushings?
I haven’t asked Hawaii Surf directly yet, because so far they’ve never answered any of my e-mails, no matter if I wrote in English or had somebody help me to ask in French. They also disregarded my request that I sent with my order :?.
When did you buy yours?
