ChoppersUS has weld on brackets. I couldn't see anyway to just bolt something on, and would you trust your face to a couple of bolts? You could go with a drum brake hub, they have some with dyno power too. But you'll have to strap it to the fork too. So either way your looking at some work. Why not just replace the fork with one that has the brackets already on there? I think ChopperUS has them too. L8R.
