I put together this list of salvage yards in the US that had a VX, and another with a Rodeo. It's about 15 months old, so some won't be accurate I'm sure. But since Troopers are so plentiful in salvage yards, I bet these same yards will have a ton of them.
You may need to go to Post #4 for the link in an .xls format.
It lists the State and phone number for all of them so you could start calling about the Trooper plates. Not sure if the 800 numbers work from CA..anybody know?
I'm guessing they won't ship to Canada, but I can get them and ship to you, since I have some spare time on my hands.
