Doc,
I'm working on a mod that is very inexpensive and will retrofit any non-'05 carrier so that it will accommodate the center licence plate bracket. It is made of inexpensive plumbing parts, except for the SMA bracket:

and the H2 licence plate lamp-housing-socket assembly. I will post details soon but you can PM me if you like.
