Re: Build process
 

The "233" on our firewall doesn't go with anything on our cowl tag. The number is in the top drivers side corner of the firewall and would normally be hidden by the fender. On the outside of the cowl, on the driver's side, ahead of the door hinges is "2100" and some other numbers that I can't read. Any Ideas?

Keith, that's where my 69 Camaro has the seq # written in crayon and it matches the seq # on my broadcast sheet. Do you have a broadcast sheet or the build sheet? My car also has a 72 written on the middle of the firewall and that matches the 72 paint for Hugger Orange.

Re: Build process
 

The "233" appears to be written on the black paint, not under it. We have the car apart and there was no paper work anywhere. Our Baltimore built SS396 was the same. Luckily we can get GM of Canada documentation up here. I'll have to do some light sanding on the fire wall to see what else I can find. Thanks for the tip Jeff.

Re: Build process
 

Keith, instead of 233 can it be Z33 and be a Canadian RPO? Just a guess.

Re: Build process
 

Joe, it is definitely a 233.

Re: Build process
 

Keith,

It should be the SEQ# from the GM Body or Chasis Broadcast copy. Did you find either one of these? The SEQ# would be on top of the black paint.

The 69 L78 Chevelle on ebay has a Body Broadcast Copy with SEQ# 246. 246 is reproduced on the Differential Cover and the spare. These are some examples where SEQ# might appear on a car. Greg

Re: Build process
 

This probably is the last of the sequence number as it is on top of the black paint.

Re: Build process
 

I did some light sanding on the firewall. No other crayon marks came up. I did find the VIN "9B412667" stamped upside down below the round heater housing hole as well as below the rectangular hole at the bottom right hand side. I have taken pictures of everything for future reference.

Rob
Only one assembly line at Baltimore plant in 69 or two ???.

Re: COPO Chevelle trim tag data
 

Baltimore also assembled El Caminos. I wonder if the vin numbers were in sequence. If so the El Camino vins would space out the Chevelles and may cause gaps depending how they were scheduled.

Re: COPO Chevelle trim tag data
 

El Caminos were part of the Chevelle line and thus would be intermixed with all the other models during production, e.g. sta wgn, 4 dr sedans, convertibles, and so on. Often they would build certain models in groups but not always.

Numbers you are finding written on the car were done by line workers for easy recognition. They would write that number on some part etc and it made it easier for them to build the car. I had a 1999 Suburban K2500 from Janesville that had similar numbers on it. The control arms, rear axle etc had 256 in crayon and it was also on the firewall.
