...one of these doovalackies.
This particular doovalackie is off a Montesa '76 Cappra 360 Marzocchi fornt folks. It is a hose clamp for the fork dust caps as well as acting as a brake cable guide. It may be the same as other euro models such as Maico, Bully's or Katties.
I need two; one for each side. (I'm not sure if they are the same or if the other is sans the guide).
35mm forks, 57mm OD of dust cap.
A commercial source of caps and/or clamps appreciated.
