CA black plates....just picked up a car....

They can in custom form but there is no space so FGH 789 comes out FGH789. You may possibly order custom plates in the same (out of circulation) digits and run the old ones with the new tags. I doubt there would be any way to distinguish the 2 when Smokie runs your plate. It was a big deal for a while here but it has died down with the introduction of black plates again.
