Greg; Great post. To expand, I had a low mileage Camaro, Norwood built, that had a 3 digit number on the firewall in crayon. I asked the Fisher Body formean about this. He explained it this way. The number was used to track the cars while in Fisher Body. He said it could start over at evevy shift, every day, what ever system that plant used. One of the purposes was to identify when a certain body was built, if there was a problem. He said that this number had no relation to the VIN or Body number, simply a way for FB to track the cars. Also, he explained the other crayon marks. The body tag was attched after the car was welded together and primered. Once tagged, rather then make the two remaining departments (paint and trim) read the tag, a person was assigned to read the tag and write in crayon on the firewall and bulkhead what was needed to be done. Thus, the X-code on the rear bulkhead for the trim dept. (such as X-44), and a paint code plus other fisher body adds on the trans hump/firewall area, such as DY for Daytona Yellow and D-80 for a rear spoiler. Many times this code is visible under the firewall paint because the firewall was painted from the bottom up, which would mean that the top (where the crayon markings are) would receive the least amount of paint. My Yenko Camaro still had 44 (which it is a X-44 car) on the rear bulkhead. And interesting, it also had 427 in crayon on each front fender extension. A lot of trucks and full size cars will have have numerous crayon markings very visible on the firewall. Tom
