It's my understanding that the red is Coca Cola red, the same as the Coca Cola delivery trucks (which include Ford vans). Not sure if that would help or not with a local Ford dealer.
I also have a red van, but thankfully haven't needed touch-up paint. I will be very curious though if you are able to track down the paint or not, so please post back if you have success, or not.
