I have a 69 Camaro Pace Car with a build date of 04C and a VIN of 636XXX. I found another Pace Car for sale with a build date of 04C as well but with a VIN of 628065. I am under the belief that this VIN would have to be an early April car. Is it possible that this is perfectly okay? Is there someplace where the VIN's are broken down by month and week?
Steve SECOND POST Final Assembly Build Date

I recently bought a 69 Z-28. I have two questions that I hope someone can help me with. the first question is,:
Is there a differance between the body build date ( on cowl tag) and the final assembly date for the complete vehicle. If there is a differance, where could a person locate the final assembly date for the complete vehicle.
The second question is,:
Were the partial VIN numbers near the small block oil filter gang stamped. The partial VIN numbers on my 69 302 engine has a few numbers that are very readable and a few that are sort of readable and a few that are not very readable. They appear to be in a straight line.
Thank you re: Final Assembly Build Date

The final assembly build date can be estimated within about a week. The week shown on the trim tag is when the body was welded together; the final assembly date is generally 3-4 days after that. Since the tag build date could be any day of that particular week, the final assembly date could be as early as 3-4 days after the first day of the tag week, or it could be 3-4 days after the last day of the tag week.
