Chevelle Frames
I know this is correct for 1967 Chevelles and may also be correct for 1964-1966 model years as well. If this is not correct for any 1964, 1965, or 1966 models, please contact me and if you have a photo or scan of correct frame, please let me know and I'll include it.

Excerpt
from Chevrolet Parts & Accessories Manual, circa 1972.
Frame Concealed VIN (CON VIN) Locations
Typical CON VIN located on the driver side rear on top of the rail and
very difficult to read except with a mirror. Generally, the
manufacturer's ID and date code are on the outside of the rail and is
visible. Remember the CON VIN will consist of the division (depending on
the year), the model year, the final assembly plant and the six digits
of the sequence number. For example, a typical CON VIN might read
19K345678 for a Chevrolet (1), 1969 (9), Kansas City
assembly plant, and vehicle sequence 345678.
Other locations for the CON VIN stamping on frames reported are ...
(1) driver side below door on top of frame on both 1964 and 1965
Chevelles; 1969 Fremont El Camino; 1966 Fremont El Camino (as well as
'typical' location)
(2) passenger side front inside of frame rail on 1970 El Camino
(3) passenger side rear frame rail, both top and outside - 1970 Atlanta
& 1970 Baltimore
As more and/or different locations are reported, I'll update the photos and information.
