In my continued pursuit of a Blue BB Coupe, just came across one with this trim Tag:
I used the ECL decoder and came up with this:
CC indicated used with option codes for Head rest seats ( car does not have) and power glide transmission. (Which no 427/435 HP cars came with). So I have I stumbled upon a FAKE here or any other interpretation of the CC ECL?
The birthday calculator shows that vin is Jan 2 1967 and the trim tag shows Jan 4. Which is odd unless the birthday calculator is wrong. What does the engine stamp pad look like?

I requested and am waiting for the engine stamp pad pic, will post if I get it.
After the formation of the NCRS and the big block craze a proliferation of 427/435hp's appeared in the 1980's. They just miraculously found their way in C-2's. LOL.

Just sent me the partial tank sticker, shows option code for the trim: 415CG. So Trim tag stamped CC in error, or this tank sheet does not go with this car? Anyone, Buehler?
The EXPECTED DATE OF PRODUCTION was generally (or always) on Fridays. DATE RECEIVED could be most any weekday. I believe I read once (maybe JohnZ) that Tuesdays was generally preferred day for order inputs, but I think they could be done any day. I believe GM tried to do the inputs as batches 1 or 2 days a week.
Need VIN or last 5 digits of VIN to help authenticate tank sticker. NCRS might also be able to perform this. I have a few doubts about the tank sticker being original, but I could possibly be persuaded either way at this point. I don't like the "burn marks"...........

Complete VIN:
Yeah nothing perfect with this one, just possibilities!
The '67 which I was second owner of had Received Date and Expected Production Date both on Fridays. Actual production was the next Thursday after the target.
CG is much better. With power windows, (and originally headrests), without powerglide, hard top, and big tank.
I'm sure you'll get plenty of opinions, but with the tank sticker and the tags, I'd accept that as a real car. I would rather see the engine pad with paint soaked off, but I believe the other things. Rear axle code KA is 3.36 posi used in L71 on the sticker.
I can even make myself see a different angle on the second letter from the C.

VIN and handwritten number on tank sticker correlate well.
I had a lot of information in my files a few years ago, to help provide you a better (more definitive) answer. But all that paper and photos are now gone forever...........going on memory now.

Thanks for your response ! So the hand written, circled “291” and the last 2 digits of the VIN “292” makes sense? Pardon my lack of knowledge on Tanks stickers; they should be the same “292” ?
While seeing this pad without paint on it is essential to making a determination about it's authenticity, as a buyer I'd have some concerns. There are no broach marks visible on this pad, and while they may just be obscured by the paint on the pad, curved lines running left to right are clearly visible (especially in the area of the Tonawanda assembly stamp). These curved lines might be the result of using something abrasive like steel wool in a previous attempt to clean the pad, but even after using something abrasive some hint of the broach marks are sometimes still visible near the head. Because it's harder to clean the pad near the head and because the stampings themselves are usually stamped some distance from the head, people don't bother trying to clean that area of the pad leaving some hint of the broach marks in place.
I'm not saying the stamping isn't real, but I wouldn't just accept a sellers claim they are real either. More needs to be known about the pad, especially considering the questions about the trim tag and those others have posted about the tank sticker.
