Vehicle Identification Number (VIN) Plate

The Vehicle Identification Number (VIN) plate was attached to the finished vehicle after final assembly and contained the Division, Model, Series, Year, Assembly Plant, and a 6-digit sequential serial number beginning with number 100001 for each plant that assembled the 1966 Chevelle.
The links on the left will display various VIN plates from those final assembly plants.
VIN plates are required by law but have been known to be swapped to prove a Super Sport SS 396 car. Always look for the VIN plate if you are in doubt. If the VIN plate has been changed, that is a violation of the law and you should stay away from that car.
The VIN number can be found stamped into other body parts and the chassis as well.
Pay special attention to the special rivets used to attach the VIN plate. Unless you are an authorized body shop facility, even the ownership of these rivets is illegal in most states. Most 1966 Chevelle VIN plates use a 6-pointed star shaped rivet.
Also found on the VIN plate is the wording "CHEVROLET DD" where the "DD" was meant to be used for Delivery Date when the vehicle was sold at the dealer. It's rare to find any additional stamping on the VIN as dealer's tended to not do this. The two examples below do exhibit these markings. Due to the differences, it's not certain whether there was a standard meaning to the stamping, and it wasn't followed, or if it was up to each dealer to stamp whatever information they deemed necessary for a delivery date.
On the pages in the links for VIN plate examples by plant, there is a table showing the approximate last VIN for that plant for each month, however August of 1965 is listed as "unk." It is known that plants did assemble the 1966 model year beginning in late August of 1965 as there are Fisher Body Number plates indicating August, 1965.
