I know it’s different in every state but here in Cali the plate style and color changed over the years.
When I bought my 37 year old 911 it was missing the original front plate and I was always paranoid I would get a ticket and have to go in a get a set of “new” plates. Once that happens you’re stuck with them and you lose that period correct look.
The company is http://licenseplates.tv/. The only problem was that they won’t ship a replica Cali plate to Cali residents and won’t even let you bill to a credit card with a Cali address even if it’s shipped outside Cali. If you live ANYWHERE else you’re fine.
Ray in Phoenix was kind enough to be the middle man (Thanks Ray!) and I received it today. The fonts and colors are spot on. The spacing on “CALIFORNIA” is a bit off but nothing that the average traffic cop (who wasn’t even born when they were discontinued) would notice.
Anyhoo, If you're looking to keep that vintage look, give ‘em a try.
Kind of a crappy pic because it was starting to get dark but here's the replica next to the original

And the replica
