I never did. I am still waiting for someone to tell me what it is used for, how it is attached and where it is attached. as able to remove the bolts.
Service around here can suck. :giggles
I went to the
Service Manual section on this site, found the
K75/K100 2V manual, went to the
Frame, fairing chapter, looked under
K100 radiator trim removing and installing 46–20 and found this diagram. The red arrow indicates what I believe to be part #19 in your reference and shows how it is attached. If you had one, you could place it in position and might get a sense of its use. It could be for hose routing, for stabilizing the shroud on the radiator or for a combination of uses.
Maybe somebody who has one of these arrays will respond and have mercy on you.
