I also just received my no auto registration in the mail. It lists the NEW, CUSTOM license plate - and I got the one I wanted!
The plates themselves may take "4 to 6 weeks", which is interesting, because I think that means that legally, I am running around with the wrong plates now!
Oh well, just keep the copy of the request for custom plates, the old and the new registrations, and don't get any more speeding tickets!
