Generally if you’re after RB or Buff dials you’ll have to find a WeChat seller. I’ve bought several custom reps with buff parts through the WeChat seller HKRwatch. HKRwatch is NOT a TD here (or anywhere that I’m aware of). But he did study English in Canada so unlike many WeChat sellers he’s very easy to communicate with if you don’t speak Chinese. Use all reasonable precautions if you decide to go the WeChat seller route. WeChat is the Wild West, only the paranoid survive. HKRwatch has always treated me fairly, but even so, I would always buy through a TD if I had the choice.
