Dennis, Hanso got these from the US - same place as Mr Mexican I recall.  He MIGHT have a set for you if you ask him nicely.  
 
As you can see, I didn't install the blue halo.  And the bike needs a clean.  
  I have some stainless tube which Im going to use to hide the bolt and make it look like ma proper mount - when I get to it.  
 
Tip: don't try to drill the holes in the indicator stems as that have a hard metal insert that heats up and melts the plastic.  Get bolts that fit.
