I can get you one (or two) from Japan.
However right now the only ones available are entire door cards from either side.
I can still get it to you at a decent price if I remove the piece you are looking for and just ship that.
That's actually pretty good. Do you have the part numbers to them? I may order them next summer or ask for them for my birthday. Since my list of mods for spring install have piled up lol Sending you a pm later today about our conversation.
