It was long enough ago to not be very relevant. Maybe 13 years ago. Back when you had to be in line on January 1st to get a SB100 number. I asked and learned which DMV, CHP, Bar etc to visit and no problems except the arduous process it took.
I bought from Vintage, and at the time Jay helped as much as possible from across the county.
But it was the same process and my only 2c worth anything at all was to ask the people that have to make their living selling cobras in California how to register them. One would think they have a vested interest in this exact info.
What do I know, I'm just a lurker.
