66 SPID sticker language - share and learn!

"Z62 - CUSTOM GROUP
Z62 - CUSTOM C&C EQUIP"

I have seen it both ways in stickers above, you could decode the vin to see if one of the assembly plants matches yours and decide which to go with.




"On my metal ID tag the Z62AA is stamped in the "TRIM' location.(see picture)"

On my trim tag, it's just Z62 and 544. no extra letters.



"
I think the information would have to include the assembly plant and year to be really useful. Obviously different plants or different years used different wording. Just my 2¢ worth..."

On the year, these stickers are only on 66's as i understand it? At least for this thread, 67-72 have their own threads with a ton of information.

If these were really mainframe printed with chain impact printers, and written in cobol, my guess is one group wrote the program, and did the data entry on the codes, and then sent the program copies to each assembly plant. 99% of the codes would read exactly the same, and if an option was changed or adjusted, the tech guy at that plant would likely change the relevant code.

That's just a GUESS, but that's why i'm thinking that 99% of these codes are identical even between series, down to the punctuation (like CU. IN. V-8, but another plant doesn't show CU IN V8. or CUB IN V8). So, my personal feeling, is that you could lift an option code and description off a similar truck, and be pretty damn sure you nailed it.

Although I have had a few '67-'72 trucks I am new to the '60-'66 trucks and didn't realize there were no SPID's before '66. So I guess the only thing that might help is listing the assembly plant.

As long as we are discussing the details of the SPID stickers, I wonder why mine is the only one with the white band and number at the top? My guess is that it was probably not meant to be there. Does this make my truck more rare/valuable? lol

good question. My 66's SPID (shown below) did not have the white stripe on top. In later trucks (a 72 shown below, bottom), the white stripe was there - and sometimes numbers were in them.... And I don't, for the life of me, know what they mean. Maybe yours was a very late production year 66 truck (?) and they switched over to the 67-72 SPID style? (doesn't look like that - yours still has the "serial #" nomenclature vice the "VIN" label). But, I did note that the number in the top white row of the 72 and your 66 is a 6 digit # - some sort of sequence, etc?? Maybe production line info/sequential, who knows. It doesn't seem to correspond to anything else in the VIN ending numbers, etc.

Heres another one with the white band on top. http://67-72chevytrucks.com/vboard/s...d.php?t=525857
