I am not very happy with the plastic hub that came with my Xcell gasser (#1005). It seems to have some play. Do any of you guys know what parts (and numbers) I need to shop for?

When searching through the MA site, I found a metal hub but I am not sure if I need top get a whole bunch off other things I see there. They also show a flybar system different than the stock, but I need to know if these things will fit together! Is there a complete upgrade package?

Thanks!
