Re: COPO Chevelle trim tag data
 

The VIN on a 1969 Chevelle is stamped below the heater box round hole on the firewall and then in an area just below the heater box area and to the right.

Re: COPO Chevelle trim tag data
 

I have a collection of over 200 1970 Chevelle buildsheets.As an example of two built 10/27/69 at Kansas City Leeds plant:Chevelle#1 VIN#121991 with a Job sequence#3389 and Body#193705..........Chevelle#2 VIN#121931 with a Job sequence#3302 and Body#209554.These are both Convertibles.I have seen one Chevelle have as many as 7 buildsheet copies from the Arlington Tx.Plant.

Re: COPO Chevelle trim tag data
 

So body number and build date don't seem to be very meaningful. But the VIN, SEQ # and build date seem to have a relationship.

Re: Build process
 

I mostly agree with Greg's info.
Fisher body built the body when the car was scheduled. But for 69 Camaros, VIN's were not assigned until the car passed thru to the Chevrolet side. There, they were queued into 5 or 6 different buffer (holding) lines and sent down the main line according to the sequence (aka rotation) # assigned to the car.
Chevrolet imprinted ALL partial VINs, that's why those #'s rust, the car was already painted.
John Z has written some of this up, but it needs to get pulled together into an article.

Re: Build process
 

Kurt, would that be the Seq # that is on the broadcast sheet or a completely different sequence number? And how did the VIN get on the broadcast sheet if it wasn't known when it was rolling down the Fisher Body line? Did they assign it after it was done on the Fisher side and print out all new broadcast sheets once it was on the Chevrolet side?

Re: Build process
 

Yes, that's the sequence # on the broadcast sheets.
The broadcast sheets are only for the Chevrolet side. When the VIN was assigned, printers throughout the plant printed the sheets out.
Fisher Body was responsible for the firewall back (so seats were done by Fisher). Fisher had their own sheets and also had UOIT's. Not much Fisher paperwork around for 1st gens. [img]/ubbthreads/images/icons/frown.gif[/img]

This system is still the same today. Just they have more than two forms. I have a mostly complete set from the Ford Atlanta plant, I think there are 5-6 different sheets. And every Taurus has one on top of the gas tank (kinda like LA cars). [img]/ubbthreads/images/icons/smile.gif[/img]

Re: Build process
 

Our Chevelle had "233" crayoned near the top of the firewall above the fuse block. Any clues on what that meant?

Re: Build process
 

Keith, does the 233 match any of the trim tag numbers? For example is the last three digits of the number in lower right hand corner 233?

Re: Build process
 

Check the list...and the answer is "no"! Yet another mystery!

Re: Build process
 

Not really a mystery. The sequence # was (and still is) the tracking # during production. It does not show up on the cowl tag, just on broadcast sheets.
