Good luck, jimmyzfu used to sell CG's on ebay, don't think he does anymore. Too bad, I got one for my 005 rep and it's a nice piece. davidsenjpn sells entire case/CG combos so he CAN get the part, although he probably won't sell you just a lever.
I've been trying to get a titanium CG/lever for a while now to upgrade my old 118. It's interesting how hard it is to get upgrade parts. I went to a couple of dealers from whom I've bought at least 1/2 dozen reps from each, figuring they'd help out a good customer. I figured wrong. I offered to pay up to $50 for a frigging CG and they're like "sorry, it is impossible to get that." I can't believe somebody in China can't get out of bed for the easiest $50 he'll ever make, but them's the breaks.
