The third 7 is really a Z since this is a Fremont built car, built the 4th week in Nov as denoted by the 11D and ST means Style and its a 67 SS car. Hopefully Dale or Mike can fill in the rest for you.
Fremont plates have a hand stamped number on them, often stamped sideways like the number "8" on this one.
Also note that sometime around the 2nd week of December (12B) the lower right corner number changed from the 'nn nnn' format to 'nnnnnn'. I have 12B tags in both formats. The 6-digit formatted number is also found on the Body Broadcast Copy sheet and ties that sheet to the car. The earlier format may be the same thing but I haven't seen any early Body Broadcast Copy sheets to confirm this.
The VIN is what it is.. 13817 is an SS hardtop..Z is Fremont Calif built and the rest in the serial number of the car.. doesn't tell you much more, we could tell you when the car was built based on the VIN, but that info was given to you via the TRIM TAG
Chevelles, and all GM division vehicles I'd assume, were sequenced regardless of series or model. 1967 Chevelles begin with sequence number 100001 for each plant and ran consecutively until the end of production. Your 114107 means your particular SS was the 14,107th Chevelle built at Fremont in 1967. While they tried to build as many like cars as possible at a time, your SS could easily have been built between a 4-dr station wagon (e.g. #114106) and a 2-dr sedan pickup (e.g., #114708).
As noted the 13817 on the VIN indicates a Chevrolet (1), SS396 series (38), sport coupe body style (17), followed by the last digit of the model year (7), the single letter assigned to the final assembly plant (Z for Fremont) and the sequence number assigned the car before it was built (114107). The style number on the trim tag, 13817, (or Fisher Body Number plate) will 'usually' match the frst five of the VIN but they do not mean the same thing. That is, the style number on the trim tag does not indicate a V8 or L6 engine the way the VIN does. I have quite a few trim tags with a style of, say, 13617 but the VIN reads 13517 meaning a L6 Malibu sport coupe where the trim tag may lead one to believe a V8 when it was really born a 6-cyl car.
In 1966 and 1967, there were no 6-cyl SS396 cars (obviously) so the style number (13817 or 13867) on the trim tag would have to match the VIN. In 1968 the sport coupe changed from a '17' model number to '37' but the same analogy applies, no such thing as a 13737 or 13767 car.
I even have several examples of 1965 Chevelles (when the Malibu SS could be had with any L6 or V8 engine) where the trim tag indicates a style number of 13837 and the VIN is 13737 and they are 6-cyl cars.
Bottom line, unless it's a 66, 67, or 68 SS396 series Chevelle, the style number on the trim tag may or may not match the VIN as far as the 3rd character goes. Some years' series cars only came in V8 versions but don't just assume an even 3rd digit in the style means it is/was a V8 Chevelle. :thumbsup:
