* It's not known for certain which (if any) plants began 1966 production in August as was normally the case in this era. There is evidence of very late (August, 3rd week) 1965 models still being built at Baltimore. Only one August dated 1966 body plate has been found to date (see plate below) and the body number listed is very much out of sync with similar body numbers for the particular style.

Note this 1965 Baltimore plate is also body dated August 3rd week. The sequence number of this particular car is at the end of the 1965 production year for Baltimore making it very unlikely the 66 SS396 tag above is real.

⁽¹⁾ Chevrolet's published U.S. production figure for the 1966 model year are 447,364 units. Subtracting the total of last reported VINs of each plant (446,633) from the published figure leaves 731 U.S. built Chevelles unaccounted for.

Chevrolet's Accumulative Production Report puts the Canadian production total at 23,688 while Canadian Classic Chevelles & Beaumonts reports 20,112.

Caveats and Disclaimers:

The numbers shown are reported last VINs from each plant per month. The numbers above those in red are instances of matching VIN and Fisher Body plates to show VINs/body dates outside the published numbers. The Fisher Body Number plate build week not match the calendar week; meaning an example body date of 04A may not be the first physical or even calendar week of April. Productions are scheduled well in advance of actual build date and given it takes 3 to 4 days to physically build the car once it is scheduled, you can see where the body date will not always match up with the VIN sequence. Obviously the body plates, and the associated information, are stamped when the cars are scheduled, not as they roll by a particular station. Cars with 04A body dates may run into week 04B of production. GM wouldn't just toss out the existing body number plates with 04A just because the car didn't physically get completed until the following week.

In reality, don't place too much emphasis on the body date as opposed to the last reported VIN for a given month. The anomalies shown are shown for that very reason. It does happen and that should not be a basis for worry that your car may have had the body plate (trim tag) and/or VIN altered.

If you have trim tags/VINs plates with dates and sequence numbers that don't fall into the range of those shown below, please email me the trim tag and sequence number and I'll post the oddity. Email it to me at
