On a numbers matching 67 L79, if it is indeed numbers matching would the last 4 digits on the frame be the same as the last 4 digits on the engine?
I have someone that is looking at purchasing an L79 and I had read someplace that a numbers matching engine number would include the last 4 digits of the body serial number
on the stamp pad there are two sets of stampings. The first group of stampings is a derivative of the VIN. This should be the last six digits of the VIN preceded by the year of the car so if the VIN # of a 1967 is XXXXXXXXX123456 than the stamping would be 7123456.
The second stamp grouping on the pad is the date code and two-letter engine suffix code.
The same VIN derivative would also be stamped on the frame.
NO offense intended, but if you or a friend of yours is looking at purchasing a Midyear, especially a numbers matching car, and you aren't familiar enough with them to already know this fairly basic information I'd STRONGLY suggest contacting someone in your area such as from a local NCRS chapter, that IS familiar with these cars and what to properly look for to inspect it for you.
With the market value on these car and the premium that a correct numbers matching car typically brings, there is a lot of faked up cars out there that are being passed off as the real thing when they aren't and if you don't know what to look for it's easy to get taken.
Again, no offense intended, this was just friendly advice based on reading between the wording on your post.

The sequence is 71 followed by the VIN derivative comprised of five digits, not six.

if it was changed after '65 I wasn't aware. In '65, which is what I have, it was "5" (for the model year 1965) followed by the last six digits of the VIN. It's even spelled out this way in the '65 Judging guide. My '65 has the original motor in the car and corresponds to this.
Goes to prove my point also...... have someone very knowledgeable inspect the car. While i know my '65, if they made a change in the way the stamping was done in '66 or '67 I wasn't aware.
According to the '67 judging manual, the last SIX digits of the VIN are preceded by a "7" for 1967 and should be 3/16" in height.
Then the other numbers on the pad will identify the motor type, HT for a L79 4 speed, HD for L79 4 speed with AIR, HP for a L79 4 speed and A/C, and KH for 4 speed, AIR and A/C.
Too much stuff to list to look for as well, all the correct components if you want a correct matching numbers car worth the money.

The "1" is a placeholder, for all years (because less than 100,000 were built each year), but it's legally part of the VIN, which is six digits long; the single preceding digit is for the model year.
Barry, John and Scott, I believe you are missing my point so allow me to attempt to clarify. In this case the model year, 7, is followed by the placeholder, 1, which is followed 5 characters representing by the balance of the VIN. Barry indicated the following: "than the stamping would be 71234567." By my math, there are six characters listed there after the number one, when there should be five. Moreover, in my opinion, the term "derivative" is generally understood to define the numerals after the placeholder. Regards

my typo mistake on the number than, I meant to put SIX digits after the "7" which is how I explained it in the text. the last digit "7" in the stamp pad example i used shouldn't have been typed there - I got too carried away on my typing and didn't stop in time.
I'll correct my post on that.
The placeholder "1" is still considered part of the actual VIN number so it its "7" followed by the last six digits of the VIN (the placeholder "1" is part of the actual VIN)
