I am beginning the restoration of my 1971 S coupe. I'd like to give the concours restoration a try. I have the tub all in primer and want to know what is the correct color black for the undercarriage. Also is the interior floor sections supposed to be black or the color of the car. What about the inner wheel wells etc. I guess what I really need is a pointer to some source or wealth of information on this subject.

Thanks in advance
David
