help needed for french registration MERLIN TF / LYNX

[pierresaulnier2000]

hello everyone
i bought a few months ago a 1987 merlin tf, assembled in johannesburg as a "lynx".engine is a ford cortina type
the serial n° is CCA13482M, actual registration n° DTG446T.
the french administration ask me to furnish them a conformity attestation and aidentification ceertificate from the constructor, these items are needed to immatriculate this car in france.
please can anyone help me, 'cause i'm a little desapointed with this problem
bests regards, thanks by advance
