My friend who recently got a 6004 had the badminton clamps shipped with his machine. I was thinking since you have a 8800, it was probably made the same time as tbuggle, because the likelyhood of a 6004s selling much more than 8800s. Gamma does not offer them as replacment clamps on thier website. So it must be a recent production change.
