The dates on the inner A-pillars,outer rockers,cowl sides and inner roof would be the critical ones. Even if the car were resurrected from a backhalfed race car or even tube chassis car,at least 3 out of those 5 should have survived. Somebody could claim that the face of the firewall,floor,frame rails,package tray,quarters and tail panel were replaced because the car was a full blown race car,but the firewall with at least the a-pillars or outer rockers should be original. Just my $.02
