i asked my SA about opening up my order and they said they can't. i'm in the same boat. i ordered on 10/22.So I'm curious about this as well. When I ordered on 10/5 I selected MYLR White on White Gemini. Now Silver is an offered free color. I'd definitely go to MSM if offered the opportunity to do so prior a VIN assignment and no change to price. I think it will look pretty nice in that color with a matched tint all the way around
below is their response:
That option is only available for vehicle orders placed after a certain date, to which yours does not qualify at this time
