Paul-
I would have got you the plate when I was out there...but there was no time...sorry!
Why dont you call them up at 714-633-3521 and ask to speak to the sales manager...then explain what you are after. I would bet that they would send you new metal ones (They still have them)...ask for the license plate inserts,too!
Here is their website
