I've got them on mine....you have to bond them over your existing blanks though. I had washer jets so I cut them down enough that they sat in the recess of the carbon blank and still had the threaded section with the nut if you get what I mean.
What a brilliant idea. Do you have any pic's ? How do they sit ? ie would you know they are not proper blanks ?
