Good luck!
Planet may well have some bits and pieces floating around, so give them a call and talk to Jack Wood about it.
Otherwise, you are going to be shopping on the web in the US. G3 paintball is your best bet, or ICD direct.
As for the Chaos stuff... Not that I know of. Your best bet is to go to
http://www.dcpaintball.com and ask Defiance.
If you find anywhere, post back, I could use the address as well.
Later,
