CA is going to insist that you have EVERYTHING that the manufacturer had on it when it left the factory:
Cat.
Exhaust Gas Recirc valve.
Air injection pump (if so equipped).
All vacuum lines under hood (should be a diagram pasted to the firewall).
All devices (charcoal canister(s), flapper valves in the air cleaner inlet horn, vapor line to fuel tank, etc.)
Original carburetor (or Calif Air Resources Board-approved substitution) aith all accessories.
I don't know any web-based source.
