Rodallg,
The smart move here would be to go to a certified smog tech in your area (where you live, and the vehicle is registered) and get his input on just exactly what you will need and what he will have to do. There are different enforcement rules for different areas of CA.
I used to know all the areas. This web site may or may not be of any assistance to your inquiry.
Smog areas Class and weight of vehicles also makes differences.
