Rod, here is a picture that someone on this board has posted in the past for 68-69 GMC VINs. I do not recall who it was but I am reposting their picture here. It came out of a manual different from mine, but the picture is almost identical.

In reference to your last picture of C9S107047P100025,I have that same example in some Canadian 910-960 shop manual for 1968 (with a 1968 VIN year! typo?), but I have never seen the Canadian GMC's posted here or on ebay at all like that example. 1967 &1968 Oshawa GMC VINs have all been C9S1471100001 format so I wonder *if* that C9S107047P100025 format ever made it into production use but only into the manuals? Kind of like the manuals where printed and then engineering changed their mind as to the format? Me thinks that.

The Canadian Parts books (most intersting of the bunch) makes mention to a "NOTE: V.I.N Block contains abbreviated model designation and complete serial number." With some examples broken down for both Chevrolet and GMC VINs. It also covers 62-66 VINs -- thus the suffix of A,B,C... etc is covered. The 71 GMC Service manual makes a reference to that lingo as well but it doesn't make sense in the way they word it for GMC Models. Only on a Chevrolet Model number would the "how-to" work right. Hmmm. Another funky misprint me thinks.

I have yet to find any GM manuals covering 1967 GMC VIN as like CM2590DPC1001B with a break down of it or explaining it. It's like nonexistant in the literature. *sigh*. The 1967 GMC Shop manual only covers the Model breakdown that's it. No VIN info stuf..

BTW, I owe 90% of my GMC VIN Knowlegde to you Rod for all the replies to peoples posting here on the board that you've done over the years. Thanks. I only had to dig for the other 9%. Still missing that 1%.
