Vin number question

CA cars got the C.A.P package and no 64-5 273 driver side exhaust pipe supports (I think that was correct? ) The Detroit plant got the rust belt production without C.A.P. Maybe Hawaii didnt get the C.A.P. so no LA plant cars? "LA" plant was actually in City of Commerce, a city within LA county and a Ford assembly plant was right across the street. Its a high rise office building now
