I got the 7.1"'s for the batwing and I have a shark. Not sure how or why anyone would need these but I just paid $80 for teh Road Glide version and was told that they are not usually sold separately. So, if anyone needs them they can have them for $80 which was told is cost by Bill at BT. I don't need them. PM me if you are interested. These are bigger than the 6.5 adapter rings that are out there.
