Just replied to your PM, sorry, didn't see this post.
I did not have to modify a thing. They swapped right out. They do not touch the grips, I have them set for the closest reach on the clutch and it almost touches the grip at full grab, but then further out the higher in the number settings you go. The brake lever I have set at 2 and it is nowhere near the grip.
My only minor complaint is they are a little sloppy in the vertical deflection, but I also thought the OEM's were sloppy that way too, so no worse. I've thought about adding a small washer or two to reduce some of the play, of course not enough to restrict movement.
When I said the "site that shall not be mentioned" I was referring to EBay tongue in cheek.
