To help clarify
things, I have inserted the VINs that appear to be missing from the runs of numbers. These inserted numbers
will be in red and have a ? where the car number would be. The number of "missing" VINs varies depending upon
how you count them. I come up with 41 VINs missing from inside runs. Of course we could be missing the beginning
or ending VIN in a run and we would not know it.
VINs that are duplicated are in purple. There are 21 sets of duplicated numbers.
To the right of these colored entries is a potential explanation in blue.
Also in blue at the end of the list are four cars that had 5 digit or 7 digit VIN codes entered into the list.
The green entries are cars known to exist
that don't show up on the list at all. Often they fill in a missing VIN spot perfectly. In
some cases they fall between runs. These are cars that Joe Ward and I came across while compiling data on as many cars
as possible. At present I have some basic option data, or at least confirmation from a source other than the NASCAR
list, for about 800 cars. We found confirmation of the existence of 15 [16 as of 2010/02/01] of the 41 (inside a run)
missing cars. We found evidence for another 8 cars that are not on the list and fall between the runs.

Below are a series of emails that I
sent to Ken Presley, noted Superbird restorer. These emails detail the sorting process leading up to the list to the
This will be the first of several emails containing various Excel spreadsheets
with Superbird VIN data.
Please find attached an electronic duplication of the paper version of the Nascar Serial
Number list that we all have. The electronic version is identical to the original in all ways except that I have corrected
a few of the obvious typographical errors. I only corrected those that were obvious mistakes. Anything that was
open to question, I left as is. I also went back and checked a 1969 calendar to see what days of the week corresponded
to dates on the list. It appears that this was a Monday through Friday affair. It shows no cars arriving or shipping
on Saturdays or Sundays.
More to come,
This spreadsheet is the a sorted version of the original Nascar Serial
Number list. It is sorted by VIN number highest to lowest. As you know, this makes finding a given car much easier
as the original list is not in order by vin. This list still contains all the duplicate vins and is missing the vins
that one would expect to find in a "run" of vins assigned to Superbirds.
One interesting thing is the
apparent tendency to build large runs according to engine type. There are stretches of U and V codes.
The attached spreadsheet is a version of the original Nascar Serial Number list
that has first been sorted by engine code and then by vin. I come up with 666 V codes rather than 665. This may
be an entry error on my part or it may be a typo on the original list. The important thing is the percentages which
are not significantly altered by one car.
More to come,
This is where things actually start to get interesting. This spreadsheet
is the Nascar Serial Number list sorted by vin number from lowest to highest. As you know there are many duplicate vin
numbers on the list and there are a number of cars that have appeared that are not on the list. When I found a duplicate
vin I put it in purple. Then I put spaces between 'runs' of vins where there is a break in the series of vin numbers.
The cars not on the original list that are known to exist are in green. The vins missing from the middle of a run that
one would logically think should be Superbirds are in red. It is not surprising that a number of the cars not on the
list fit perfectly into the list. Even more interesting is how many of the cars not on the list have vins that are very
close in format to the duplicate vins or missing vins. By this I mean the numbers could have easily been transposed
when transferring the data to print. For instance 178678 shows up recorded twice but 176668 is missing and is dead center
in the middle of a run. I believe it is very likely that someone simply made a mistake at some point of the transfer
of data onto paper.
I imagine some unfortunate person standing outside at Clairpointe in the snow trying to read
vins upside down through an icy windshield or bent over trying to read the door tag and reading the numbers off to someone
in mittens trying to stay focused and copy the numbers legibly so that a secretary can later transfer them to paper.
I am surprised that the document is as accurate as it is given the number times data had to be transferred.
One additional item of interest is that despite almost two dozen cars being found that are not on the list, no cars with
vins beyond the highest one on the Nascar list have been found. If there were more than 1920 cars, that almost certainly
means they would have to fall between the runs of cars. I have done some speculative assessment of the total number
of cars and I keep coming up the the same 1920 number. With close to 800 of the cars on file (or over 40%), one would
expect at least one car to have materialized if any cars with a vin higher than 181274 were built.

HYPOTHETICAL SITUATION #1
assume that Chrysler was on the ball when it came to assigning the VINs to the Superbird project. Let's say that they
knew they had to build 1920 cars and, as they had done with other specialty street versions of race cars, they decided to
build a handful more than the minimum required amount. That would mean they intended to build 1925 cars. How many
cars would the assigned runs of VINs total up to if one ignores all the duplicates, missing numbers and numbers that fall
between runs? What is the total number of VINs assigned if one totals up all the runs? Well, it turns out to be
1925! If you make a number of potentially erroneous assumptions, such as; we have the beginning and ending VINs of every
run, and then add up all the VINs making up these runs, you get 1925 cars. Interesting.
To the right of the list you will
see the "Span" or run of VINs and a running total. The number in the span is not the actual quantity taken
from the list. It is the hypothetical amount if one assumes a Superbird was built for each VIN in the run. So,
for example, Span two has a total of 10 cars despite one VIN in the middle not showing up on the list.
