Original build information by VIN is not available for US produced/sold trucks until 1976/1977 model year.
For vehicles produced in Canada or produced in the US for Canadian consumption the information is available through GM of Canada.

So, if neither of those help: unless you can find a build sheet you'll just have to guess at what content is correct and make up your own list.

Once you have the content decided you can contact site member chipflyer (Jeff) at
http://outintheshop.com/ and he can reproduce the label itself for you.
