Actually they are Ken Sean mirrors url:

although they are pretty much identical to the Napoleans. $32 or $34 bucks shipped (I dont have the invoice handy).
Yes, they are dead easy to install, just remove the barends and then install the mirrors, I had to cut about an 1/8" or so off the end of the rubber to have them fit just right.
What a difference though, highly recommended!
