"The procedure is to use SPCN to register replicas in CA"
When I first read the above, I thought it said, "The procedure is to use SPCN to register Alpacas in CA." I had to make sure I was on the correct website.
"Doesn't CA still only issue 500 SPCN registrations per year?"
I don't know this as fact, but I read that during the last economic downturn, the DMV no longer limited the number of SPCNS registrations to 500 per year, and that policy continues.
