I'm talking about the bolts that insert in the drive bushings on the rear hub. On the parts fiche, it's #27, part number 90109-12429-00.

There's a rear wheel on e-bay that's missing those bolts.

I happened to find a used set on ebay today.

Researching, I saw this video: https://www.youtube.com/watch?v=Dzf1SJgcvBg

Then I had the idea - why not tap the cush drives then screw in bolts? They wouldn't be the stock size and the holes in the sprocket may need enlarging.

I just made some out of aluminum for mine. (the bushings, as i was killing them quickly). i was considering using m12 bolts though them, but inserted the stock studs back in the aluminum bushings instead.
