Clutch Bell Adapter

If you have access to a lathe (this is what it will take), you could turn an adapter to fit into the recesses on the clutch bell and use some jb weld to fix it in there. I did something similar when I first started on brushless, but didn't use it for long, since my order came in faster than I thought it would.

I think I used aluminum bronze to make the part. It's easy to work with and resists abrasion pretty well.
