I'm wondering how many cars the St. Louis plant built per day in 1966-7. If my dad owns build sequence # 100183 for the 1967 model year, and the sequence started at 100001, I wonder what day it was produced?

Re: Build sequence, 1967
Look on your data plate in the corner and you will probably see an A(August) or B(Sept.) and a number. That number is the day the body was produced. They built had 2110 by the end of the first month. (Sept.) -
Re: Build sequence, 1967
Do you mean the B06 in the upper left corner? If so, am I to understand that that means a build date of the BODY of September 6th, 1966? That is NOT the final assembly date however.....correct?Chris Enstrom

Correct....
That's the date the body was built and NOT when the final vehicle was assembled. BUT, those mid-year Corvettes with a St. Louis vs. AO Smith body track pretty closely (final assy vs. body build date) because the St. Louis body shop didn't have a lot of space to 'warehouse' completed body assy's. On the other hand AO Smith bodied cars can vary SIGNIGICANTLY in terms of body build vs. final assy date because they were shipped via rail car from Ionia, MI to St. Louis and often sat outside the plant for periods of time 'waiting' to be pulled for final assy.
The only 'correct' way to determine your cars actual final assy date is to interpolate it from the VIN number based on Chevrolet end-of-month production records (NCRS Judging Guide and Corvette Black Book). Also, there are Corvette 'birthday' calculators to do the interpolation mathematics for you (one is on-line at the Wisconsin Chapter's web site).
BUT, remember while a given birthday calculator might be 'intelligent' (knows about strike periods, knows exactly how many Sat/Sun periods are in a given month, knows then current GM recognized holidays), the calculation results are still an ESTIMATE.
Why? Nobody knows the specifics of other production aspects like addition of swing shifts to meet production targets, Sat/Sun overtime authorizations, sporadic line shut down episodes + line speed-up/slow-down pacing....
In my book, about as close as you'll get to reality is +/- 3 days, UNLESS your car just happens to be built near a given end-of-month production number....Comment

Re: Correct....
Most often, the trim tag time build code is the same or previous day that the car was completed. The exception would be bodies that went into production just before a weekend. The body line was run right next to the chassis line and within minutes of the end of the body build, it was being ******ed off the body line and dropped on it's chassis. The time from when the body was removed from the body build truck to the time it was installed on it's chassis was roughly 13 minutes. If a body tag is stamped and installed near the end of the work day, the car would have been completed the next work day but the tag code would still show the previous day. A.O. Smith bodies, as you mentioned, would be a totally different story.Comment

Re: Correct....
Chris,
Also there is a style number (67 467 or 67 437) to indicate a convert or coupe on the upper left of the trim tag and a body number on the upper right. That will tell you if its a AO Smith or St Louis body along with the secquence that that body was built in.
