Anyone have absolutely any idea where I can get one of these? I've scoured the web. I really only need the 2 metal collar pieces, but it doesn't seem to be a separate part to be able to purchase. I'm at a loss here...
First off, even in your frustration mode, when asking for help like this looking for a specific part, include what your bike is specifically, I'm having to ASSUME (A Very bad thing), by using the bike listed in your signature is your Only bike.....


Some people on this forum have multiple bikes of multiple years and models.....
Based on your signature listing of a 77K and your part number and #12 in the picture, the part number you listed in the title is a supersede of 42620-300-010, which searching the parts fiches, is the same on all K models, K0-K8 and A models, 1976-1977(with spoke wheel).
So, according to the parts fiches, you can get the collar spacer from any of those wheels by taking one apart.
You should be able to find a wheel locally(get one that the axle slides out easily!), to get the collar out yourself.
I have extra wheels but the time to remove the collar will be costly (for my time to remove and ship the collar). If I had one out and loose I'd send it to you for postage but I don't.
Note: all Super Sport, F models are different part numbers so don't bother trying them.
