Your biggest problem will be passing an emissions test. In 1969 California wasn't too strict in the regulations, BUT you still have to meet the regs of a 1969 vehical; visual and MAYBE a sniff test. The visual requirement will be that what ever California required has to be present if the car was a Ca spec car to begin with. If the car was from out of state you may have better luck.
Look for a sympathetic inspection station.
Good luck.
