As you probably know by now, I'm one of those (annoying) numbers crunchers in the hobby.

A fellow archivist and I discuss a lot of mundane and totally uninteresting, to others, topics about how assembly plants did things and paperwork on cars.

We were discussing the significance of the sequence number on broadcast sheets.

The broadcast sheet sequence number means different things at different stations of the plant and can mean something different at each plant.

Once you compile enough data you can see patterns and determine what was done, why it was done and what it means.
Our main access to information is A, B and E body cars built at St. Louis, Hamtramck, and Lynch Road.
We want to determine if what we learned at those plants means the same thing at C body plants.

Not enough is known about the C body plants as:

1) They were lower production than the A, B and E bodies meaning less documentation to start with.
2) There are fewer C body lovers than the others.
2) People just don't value them C bodies like the others. Too many are scrapped without saving any of the documentation like broadcast sheets and fender tags. Cars are lost forever.
3) I've learned C body guys just have a different approach to the hobby and aren't as interested in the numbers crunching as the B and E body folks. It's just something that isn't discussed here like other boards. That's cool. It just different.

Therefore, research on C bodies is harder to come by.


Here's what I'm asking for help with.

I have some 69-71 C body broadcast sheets from the Jefferson and Belvedere plant but not enough to draw any valid conclusions as to what the broadcast sequence number means at those plants.

Do any of you have any 69-71 C body broadcast sheets you would be willing to share or would any of you with 69-71 C bodies be willing to share information or copies of your broadcast sheets?

Here is the type of data we are looking for. It's found in the upper left half portion of the sheet.

Thanks for any help you can offer.

Here is what I know and led me to giving up trying to understand them.
They are not sequential in the same order as the VIN, meaning you could have a VIN 101 with a SO 102 and a VIN of 102 with a SO of 101
There are rumors of cars with multiple correct VIN broadcast sheets with different SO numbers.

Theoretically they count the cars assembled that day but it isn't that simple.

I use to be all over the codes and deciphering sheets but gave up and let others do the dirty work and enjoy the results.

Bottom line that even in the B & E body world there just isn't enough people that care what the number is.

You need to PM Kevin McCabe if you havent talked with him already......Kevin will shed some light on a lot of stuff

That's what I mean when I say the number means something different at different plants.

Hamtramck sequence numbers are completely different than St. Louis and Lynch Road is different than the other two.

Hamtramck numbers do tend to be sequential. STL and LR are definitely not sequential nor correlate to the VIN like Hamtramck, but have similarities between those two plants.

From the sheets above, it appears what Belvedere did was similar to what STL did but with a slight variation. We just do not have enough data on C bodies to draw any conclusions yet.

There are at least 3 people that care...LOL. ;) The data will be significant when it is compiled and deciphered.
 
I got nothing for you Doug but I love what yer doing! When you get real and start with the slabbies I'll contribute.

I'll grab a bottle of Bailey's and compile the data if you can find me 100 slabby sheets from one plant for one model year. Even with that few number of sheets, you can start to make valid assumptions.
 
I think I have at least one broadcast sheet from a 69 2dr 300, and maybe a 71 300 4dr. I know I have the fender tags for sure. Will dig them out and post up the info.
 
I may still have two of the three found in my car. Only one was really worth a damn. Slab.
 
OK I have the sheet from the 69 300.

The Sequence Number is - D 1198802
Vehicle order number - 207 B41367
VIN - CM23K9C221350

I don't believe I found a sheet in the 71 300. Also I have a copy of the window sticker and fender tag from my old 70 Sport fury...unfortunately it had no broadcast sheet in that one either. But if the fender tag info is useful let me know what you want.

Thank you. It's a start. Could you please check again. I think the sequence number should have six digits, not 7.
 
I have a 67' Newport and 68' New Yorker sheet, but that is earlier than what you are asking for, sorry. I Wish I could help.
