Headlight bushings

So, I have this beatup K in my garage...

I am trying to mount up a small fairing type headlight with cover. This thing mounts to the fork with four M6 bolts that go through metal bushings and rubber insulators.

I have the rubber bits, but no other hardware. The stupid bushings are $10 a piece. Anyone know what size those are? I don't really want to spend 40 bucks and wait a week.

Year? Model? Link to where you found the price?

Try finding something that fits at your local hardware store.

The bike is an 86 K100. The headlight is off of a K75, or something like that. They mount the same.

Since I am trying to fit some squishy rubber bushings, I was kinda hoping to get some indication of what to look for.

I can certainly try to eyeball it.

what about some 1/4” well nuts and drill out the threads ?

the inner core is brass so it would be pretty rigid as long as you kept it below 130 mph.

you can trim any excess rubber pretty easy too.

they have plastic bushings in the small drawers of the Ace or True Value but none have the shoulder unless a washer could work . heck they even have plastic washers .

I made it work with a combination of a M6x35 flange bolt, 6mm fender washer, a 1/4 inch bushing and a regular washer to go over the bushing.
