How do I go about finding out the build date for my car using the VIN#? I appreciate any help. Thanks |

Hi all,
How do I go about finding out the build date for my car using the VIN#? Your VIN would be limited to the year of production and that depends on the year of your car. Don't believe the early ones had a digit code for year. |

IF you want to do the math: purchase any of the Corvette reference guides where monthly ending VIN production figures are published. Find your VIN in the range and jot down final monthly VIN for that month. Subtract final VIN for the month before for total monthly production for your month. Use a perpetual calendar to determine number of working days in the month your car was produced. Do not count recognized holidays or Sundays; count Saturdays. Divide number of working days into monthly production for an average daily production figure. Add your average daily figure to the ending VIN of the prior month OR subtract your daily average figure from the final VIN of your month until your daily VIN range shows up. Either (adding or subtracting) will get you in the ball park. It could vary, but typical daily average Corvette production was 110-120. FWIW: beginning about the middle of March, 1978 through about the middle of May, 1978 Pace Cars were in production and regular 78 assembly was suspended. :thumbs: |
The NCRS Corvette Birthday book can tell you with reasonable accuracy what the birth date of your car is. Alot of research went into the book. I just picked up a copy at Carlisle.
What's your VIN? |
Register on the C3 registry and they will tell you the build date.
|
All of the books and calculators are just educated guesses based on statistics and a limited number of data points. All of them also have known and documented errors.
I don't understand why someone would use those in preference to the trim tag date on the car.............. |
I-Phone App
Believe it or not ,there is an I-Phone app which supposedly gives you thebuild date using the last 5 vin digits...
Some one post their last 5 VIN and year and we'll see how accurate it is. Neal |

corvette birthday calculator... good for ballpark figures... not as good as your trim tag though...

And how would they 'know' their build date?
I just offered it up ..it's not my APP ,I didnt develop it , not standing by it or charging anyone $.01 for looking it up! Done, Neal |
No, I'm again pointing out the irrational step of relying on calculators vs. simply looking at the date on the trim tag. Why make easy things difficult?

JBaron: What's your time/build code? Upper right corner of your trim tag. http://i106.photobucket.com/albums/m...0Mike/71-1.jpg J28 on this example. TRIM and PAINT are the factory codes for interior and exterior colors. :thumbs: |

The dates in the book are within a couple of days of my trim tags on my mid year and 68. No trim tags on the solid axles. I really wanted to check on my 61. |

You can get reasonably close. :thumbs: |

Use Noland Adams' calculatioin method. If memory serves, it's in his Volume I Restoration Guide. I paraphrased it in my post. For '61, they may have been working less Saturdays than they did for the C3 model years.
You can get reasonably close. :thumbs: Noland was also involved in the Birthday Book along with John Hinckley. Two pretty knowledgeable people :thumbs: |
