I just brought Contemporary S/N 3098 home and based on discussions, realize now there were three generations of molds with the third being the most refined and symmetrical. Does anyone know whether my car would be first or second generation? I don’t have CCX prefix so I presume it is not third. First was more original I guess but also more different side to side. Was second generation a middle ground? What do I look for, measure, inspect, to determine which molds used for my car? I want to know all I can before starting restoration. Thanks.
