Early 80's Vented Number Plate

I'm building a 1982 CR 250 Works Tribute Bike and I need an aftermarket square 83 style Vented front Number Plate in White. The ones with the holes, that were real popular and then all of a sudden they weren't. A fad. I thought they would be easy to find but they are not. I have a red one on a project Maico I could paint it white but we know that isn't going to last long. Anybody know of a reproduction ?
