the BIG picture of VIN and fender tag creation

[RzeroB]

The VIN has nothing to do with build order.  It just means that 12 other cars were assigned VIN numbers before that Challenger.

  I think I got it now. So the Production Scheduling Department would transform the vehicle order into a VIN and production sequence number (among other things). Then the Production Control Department would assign a Scheduled Production Date (SPD) based on parts and sub-assemblies availability (among other things). However, due to an infinite amount of variables that could influence production, the cars may not of have actually been built on the SPD. As such, the actual order in which they rolled down the line was mostly determined by the Production Control Department's assigned SPD but could be deviated by those aforementioned variables associated with the manufacturing process.

So based on my previous example of Barracudas and Challengers, the Hamtramck Production Scheduling Department probably assigned the first 12 VINs (100001 - 100012) and production sequence numbers to Barracudas and then assigned a batch of subsequent ones (100013 - 100???) to Challengers. Then the Production Control Department, based on their operating guidelines, would assign the SPD and the cars would start to be built. How they came off the end of the line would of course be determined by the SPD and whatever production variables that may have been introduced during the manufacturing process.

Maybe I'm over-simplifying it, but I think I got it close enough to where it now makes sense to me. Thank you Sensei Burdar for enlightening me, you have been most helpful.

Many, many years ago, and every few years, I had/do research to early built E-Bodies.

Yes. The 0B100001-0B100012 are E-Body Plymouth VINs. 0B100013-0B100029 are E-Body Dodge. 0B100030-0B100327 are E-Body Plymouth (with one exception 0B100113 possibly being a Challenger). 0B100347-0B100772 E-Body Dodge. I do not have every car in my files. Barry does not have too many early cars either, BUT he has a list of ALL make and models at the plant. VINs will be sequential, but make, model, and body style will varry. An example: perhaps 0B100250-0B100280 might be A-Body Plymouths (I don't know any A-Body VINs). Just an example.
I have collected thousands of VINs for  my own personal education.
I can only add, that Barry Washington can help with his data base.

... I learned that Challenger JH27G0B100013 was supposedly the very first Challenger to come off the line at Hamtramck. I was like "100013 is the first?? How can that be??" But it would make sense if they rolled a dozen Barracuda's off the line first before the first Challenger came off the line right?

I will wager $1,000 that is was the first Challenger built. Aside that it is the lowest VIN for a Challenger.
Chrysler assigned JOB NUMBERS for specific cars that were to be built a certain way. That certain way, were internal orders. Mxxxxx VONs.

Example: BS27V0B100004 An executive decision was made to built this specific car (`cuda440-6 D21 EW1 PRX9 N96 P31 P37 R22 etc.) and was assigned JOB NUMBER 8.

There may have been 250 cars slated to be built by the factory for what ever purpose. JOB NUMBER 1 through JOB NUMBER 250 (We don't have an exact figure) ALL makes and models.

BS23R0B100003 is JOB NUMBER 5
BS27V0B100004 is JOB NUMBER 8
JH27G0B100013 is JOB NUMBER 6
JS29R0B100015 is JOB NUMBER 12
JS27V0B100121 is JOB NUMBER 166

We think that the JOB NUMBER cars were suposed to be built at least in groups of same make and model. It has been proven that some cars were built prior to others (out of sequence) just like the actual assembly line.
I would still bet money that the early JOB NUMBER cars were built first. Just logical for the "new concept vehicles" to be built for their early purposes. Mock up, repair assembly hour determination, destructive testing, advertisment, or what ever the reason.

0B100010 and 0B100121 were the advertisment and testing cars for magazines (among others). I bet the "lowly plain Jane" EW1 JH27G0B car was built first to make sure the new body style worked out.
Intereting that we never saw BS23R0B100003, BS27V0B100004, JH27G0B100013 in the lime light back in the day. Oh yeah....they were all EW1 Alpine White cars.

My data base is limited to E-Bodies and these past 13 years - honed to just the 1970-71 model years.
There are many early cars that have a JOB NUMBER. Plymouth Road Runner. Dodge Polara. etc.
