Question about Radiator mounting COLLAR left side.

[Magellon]

I looked down on the left side of the bike the other day at the radiator mount and there was just the rubber mount with the threaded stud sticking through, it looked like a nut backed off and is missing.

 I went to the microfiche to see if there was a nut missing and all I see is a "COLLAR part #40521-437-000 item#26". Don't see a nut in the pic for either side. Cant see the right side rad mount, its behind stuff.

So my question is does the COLLAR have threads? What holds it on if it does not have threads, and how would you tighten it up if it had threads? Also can I still get one to replace the one I'm missing? Ok so that's 3 or 4 questions.

Here's the link if anyone's not sure what I'm looking for

Thanks for any help.

Been there done that  it is threaded, but nothing goes on it, I guess some one in the design dept thought it needed a nut, but none were installed at the factory. The top bolt holds the radiator in place, take it out and the assembly slides out the left side.
