I bought one of these: http://www.motorcyclestorehouse.nl/product/982285 made by Hells Kitchen Choppers.

As it turned out, it did not fit my 2012 Fat Boy 103" - I had to grind it down because it was too thick to fit on the axle (even using the thinner nut that came with it):



Later I saw this one in Geneva: http://www.bossparts.ch/products-pag...e/b-ch-m78-ob/ - much more to my liking (but of course it had not come up on my extensive google searches).

Hope my experience may help somebody.

 

Just had it (partly) powder coated here http://www.fullrangefinishing.co.uk/
