    Here are two references that basically agree in their information.

    https://www.jeepfan.com/tech/decodin...ers-1955-1971/

    https://www.4-wheel-parts.de/en/info...ber-41-71.html

    Both agree that the 1965 CJ-6 should have a 13 digit serial number, not just the 9 digits you show. You are missing some numbers. But, the 9 digits do give some information about your CJ-6's configuration:

    First two digits 84 Designates a CJ-6
    Second two 05 Open body
    Fifth 2 Smog reduction
    Sixth 6 Drive designation, only digits 1,2 or 3 are assigned. 6 is not valid
    Seventh 7 V6-255 engine with emission controls
    Eight thru thirteen 42xxx Sequential serial number- missing digits

    Good Luck – post us a picture of your Portuguese Jeep.

    Good Morning.
    First of all I would like to thank you for the answer.
    My serial number only has these numbers.
    I can hardly go for a photo of the serial number plate.
    Thank you

    Welcome Fernandoportugal!,,

    Your CJ6 may have been produced in one of three locations outside of the U.S., South Africa/Volkswagen, Brazil/Ford, or Australia/Ford. This may account for the serial number difference from the information that we have. I haven't been able to verify my theory, but that is my hunch.

    Please post some pictures, for we would love to see your rig!
