missing parts

Hi everyone, I recently went on a trip and somehow lost the left arm of my Flak 2.0 XL Oakley sunglasses. The arm completely detached itself from the socket (was not broken) so I now have a pair of perfectly intact Flak 2.0 XL sunglasses, just missing the left arm. I was hoping that I could...

I’ve lost the left ear stem of my polished white Radar EV path frames. Oakley customer services say I need to replace the entire frame, though I would rather try to replace the missing part first. I haven’t had much luck on all the other regular sites (eBay etc). Does anybody have any advice?
