C2-crayon mark

[mac peppers]

i was pressure washing the firewall on my 63 and noticed the number 431 handwritten in about 5" high numbers on the firewall under the heater fan box with what looks like a green crayon. does anyone know if this number is significant or is it just the daily job number?
thanks,
mac

Re: C2-crayon mark

That daily job number will also appear under your inner door panels, on the rear bulkhead, and possibly on the dash brace, near the speedo. These numbers were cycled from 1 up to 500, then back down to 1. If it is larger than 500, then I suppose it is significant. Noland Adams' book has lots of info and pics on this subject.

Just a production line #. 1 to 500 then back to 1 again

It's the Body Shop job number - unrelated to the VIN or the broadcast sequence number that was assigned after the Paint Shop.

Re: C2-crayon mark

hmm, dash brace under speedo, number is beyond the 1 - 500 job number spec, so what is this then? Note that the car's ultimate "birthday" was April 6, 1965, so much of it was assembled in late March, perhaps the date is embedded in this number? No one has solved this one for me yet.

Re: C2-crayon mark

That's the Chassis Broadcast sequence number, which was assigned after the Paint Shop, when the body was loaded on the Trim Line; at that point in the process, the car was "locked in sequence" all the way to the end of the Final Line. The Chassis Broadcast Sequence numbers went 0-9999 and recycled.

Solved! Thnx John *NM*

John,

I may have just learned something here but I've never heard of that. I suppose it's possible but I vividly remember the job number going on body panels before the body went throgh paint but that number was always the same as the job number assigned to the body. I remember it being put on floor pans when they were still in a pile upside down, waiting to be loaded onto the body trucks. It wouldn't make any sense to have two completely different numbering systems in the same building. The chassis IS body specific and "locked in sequence" right from the very first station and the same for the body. Too many variables along the way and those variables started almst immediately when the chassis was placed in the fixture. Coil spring selection, sway bars etc etc. The same for the body. An A/C car, for example, had to be built as an A/C car almost from the first station because of the differences in IP etc.

I always try to be open minded on these things and I may learn something before this is all over but I'd sure like to hear from some other members on this.

Also, the body's were never loaded onto a different line after leaving the body build area. The conveyor was continuous and went right out of body shop/paint, made a 180 deg turn and went directly into blackout, then to hard trim install.
