Intermountain RailBox mistery (for me) parts

[Topo]

I know, I know. It's summer and my brain cells are a bit overheathed, so maybe you can help me to figure out what are these things that came with my new Intermountain R-Box cars.

When I opened the box and see this tiny yellow rings, I figured that they were some detail parts, but, for a million €, I'm not able to figure neither WHAT exact parts nor where are they supposed to be mounted.

Can you give some advice to this poor, brain-damaged, guy?

could they possibly be for adjusting the heighth of the car through the trucks? I'm just throwing an idea out there, all that comes to mind.

They might be bushings to allow you to mount the trucks with a smaller screw? I don't think they are detail parts. If the car works as built, I would just throw them in the scrap box, and not worry about them.

Well, I forgot to mention two facts:

a) These tiny «rings» are painted the same colour as the car body (the pics show they more reddish), so I suppose that they should go in a visible spot (the car sides?, the bulkheads?).

b) I have also a couple of the Intermountain RailBox cars in «late» scheme, and they came without any add-on. These «rings» only came with the Intermountain RailBox «early» scheme cars.

Russ, the cars don't seem to need these thingies at all but the curiosity itches me.

(oh, I can always e-mail Intermountain about that, but I feel that it will turn out something so obvious that I will make an stupid of me for asking about) ops:

I think an e mail is at hand, if they were for the trucks wouldn't they be the same color as the underframe?? I don't know what they would be for either!!.

I believe that because by putting the rings on the trucks they may become visible that that is why they painted them yellow

That truck spacers is the only thing I can think of too. But they should not be necessary if the car is built and gauged correctly out of the box. OMG, they cost enough so they should be correct out of the box. All IMR cars have been shipped with KD couplers for the last several years now... so these should truly be RTR. I plan to acquire one of these Railbox too.
