LOS car history & geography

[huggerSS69RS]

I purchased a 69 Camaro a few months ago which I am presently restoring and I would like to research it's history but don't know exactly where to start.
I was told the car was in CA most of it's life and found several related items in the console such as a 1982 Medic Aid card issued in Sherman Oaks, a 1978 Van Nuys Blvd parking ticket and a business card for a dental appointment in Panorama City etc. My knowledge of CA geography is limited to what I found on the internet but it appears that these places are close to each other and not that far from LOS where the car was built. I am thinking it was a black & yellow plate car but no number plates were supplied with the car.
As the car is now located in Australia I am not sure who to contact to search previous owner information and found that you can't do a online VIN search due to CA laws. I would like to track down a POP or build sheet if possible as all I could find in the car was a small piece of perforated paper under the rear seat which look to be the remnants of the build sheet.
Any advice or suggestions from the forum is appreciated.

Thanks,
Newbie

It depends on when the car was sold
I own a 69 that was sold in Torrance in October and came with the yellow on blue plates (the ### AAA style)
