Full VIN tag is on the driver's windshield post visible from outside the car. Trim tag with time/build code is on the driver's door hinge post and visible when you open the door.
Engine identification stamp and VIN derivitive stamp are on the pad on the block at the front of the passenger's side head. The VIN derivitive is also stamped on original transmissions. Location can vary depending on the tranny.
A VIN derivitive is also stamped on the frame in two places. One location cannot be seen with the body on the frame. The second location is on top of the frame rail in front of the #4 body mount on the driver's side. This stamp is difficult to see for most people, but some folks have had good luck seeing it without having to resort to magic.
From there on out, almost any original part could have a date code on it in some way, shape, or form; all of which must precede the time/build date on the trim tag.
C4s have a label listing the options and other equipment installed on the car; C3s do not have any such label. No sense looking for it.
Do you have any original factory documentation with your 68?

1.the auto trans stamping is on the dr side/left just above the pan rail,
2.the block csating number is on the dr side/left top rear behind the cyl head just above 3.the trans flange to block area
4.intake number is on the top front of manifold,
5.head casting numbers are under the valve covers,
6.rear differential number is -stamping on lower side of housing just in front of rear cover -casting is on case on top side by driveshaft yoke,
7.carb if holley is on the choke horn front
just start writing down every casting number you can find and there several books that can decipher them,some dates are in a julian code[glass,etc]
where is the other spot on the frame to find the VIN# ?,,ive found the dr side one by the #4 body mount
Hi c,
I see where you live so I assume you'll have a long winter to look at your 68.
There are LOTS of parts you can check if you're interested.
I suggest you buy a copy of the new NCRS 68-69 Technical Information Manual & Judging Guide.
This will help you to find what parts you should be looking at and how to decipher the numbers and date codes you find.
As EMike said the list of parts with numbers and dates is VERY long once you get beyond the engine and transmission.
68s can be especially interesting because they had a 'few' 68 only parts!
Regards,
Alan
You can't see the one in the pic with the body on the frame. Actually doesn't make much difference. If you found the one by #4 body mount, the other one will be the same.
I wonder how many stamping errors were made with mismatched and duplicated serial numbers. Working in the aerospace industry for so many years I have seen dozens of serialization errors even using systems that were supposedly computer "controlled". I can only imagine what it would be like with an all manual system.

Probably not as many as you think. The process at St. Louis was reasonably controlled. The worker in the pic could literally look at the VIN derivitive stamped on the engine pad and match the number in his tool. Look closely and you can just see a bit of the corner of the build schedule already taped on the fuel tank. A partial VIN (later a full VIN) was on it.
