Correct, until after the Ford Total Performance period Holley used three digit date codes. Said another way, any new car production Holley on any 1962-1970 Shelby related car will have a three digit date code. Four digit date codes are for sure on later service replacement units.
Buyers beware, there are people obtaining either new undated service bodies or welding up existing numbers on common bodies and stamping them with whatever numbers are most valuable.
