Paint code for a 400 GT of 1978

Hi everybody,

I am looking for the colour paint code for the Dark blue of 1978, for a 400 GT.
If some of you owns a "navy blue" 400 of 1978 or near, perhaps can he give me the paint code, or if you have the colour chart of 1978, you may be able to give me the good paint code.

Thank you very much for your help, I will wait for your answer before repainting my car....

Best regards to all
