Just got off the phone with hinson they said that H082 is the kx500 basket and they don't make them anymore but some are out there floating around so if you can get one grab it but hinson said that is the part number for the kx500 082 I ordered one today.
In the sales meeting on wednesday he is going to try and get a run of k5 baskets made though and will call me back wednesday evening to tell me how it went.
