8706-8708 8726 8730-31-34 , they have three bars around the center hub, also most have a little cyclone printed on them. but not all, they did replace 7 of them for me, but some will never be replaced they said they are not redoing them in uncloged versions, but I could buy most of the songs on their custom disc at $5.00 a song. yea right, BOB
PS. they said no one told them they had to replace them. they are doing it on their own.
