Problem is your Aurora is viewed as 1982 car and not covered under the California SPCNS SB100 Specially Constructed Vehicle exemption. With that exemption CARB compliant parts are not required. You just need a PCV valve as a 1962-65 Cobra of the period would have had.

I don't know if your car could qualify under SB100 since it was delivered by the manufacturer as a turnkey car and is already registered as a non-exempt 1982. Being 1982 it needs to conform to 1982 emissions standards and that means no non-approved CARB parts. Moreover as a 1982 it will have to be subject to testing every two years for registration renewal. If older than 1975 or exempted via SB100 then no further testings are required. Completely exempt.

You appear to have fallen into a crack in the regulations in that you have a Cobra replica but it was originally registered as an EPA and DOT compliant 1982 Aurora convertible roadster.

I think your only choices are to fit the original 1982 equipment or sell the car to a state that does not follow the CARB rules.

From the Internet:

"There are a growing number of CARB states including California, Connecticut, Colorado, Delaware, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, and Washington D.C. Most of these states have strict emission standards and require vehicles to be tested annually or biennially (every other year)."
