He removed all trim and emblems when he painted it in the 90's. I would like to put it back to original, but I don't know what is correct. Can anyone tell by looking a this?

Here's one from a '71 my buddy just picked up. Why does it say Custom Sport Truck instead of Cheyenne?

Clean looking spid too. The upper LH corner has come undone a bit on mine. I figure to cut the bad off, and match it with 3M protection film. May even top the entire spid off with another sheet. That is unless someone has a better idea.

Since you are pushing for an original appearing truck I'd advise against altering the SPID. Generally I advise people to have a reproduction SPID made and attach it to another restored glovebox door thus keeping the original safe and intact. Keeps you from having the dreaded repaint masking line around the SPID as well.

In a case like mine where the truck no longer retains the original, is there a way to get the correct information to make an accurate reproduction.

Yes. I don't remember what model year but it varied by final assembly location. My '87 is laminated, and I think my '80 was laminated.



Site member "chipflyer" does reproductions. I'm sure he can tell an original from a reproduction. http://outintheshop.com/



You can contact the GM Heritage Center Archives, depending on your model year. For US built and/or sold light trucks after 1976 you can send them your VIN and $50 and they will return the actual vehicle invoice for your specific truck, which includes RPO content and pricing.

GM of Canada has information reaching a little farther back, for vehicles sold in Canada, or vehicles produced in Canada for US consumption.

If you don't fall in either of those categories you are out of luck.



For the original build: The SPID is a service document. The truck is contented and all of the build information broadcast throughout the assembly plant to the areas required. The build manifest, specific build sheet, tuneup labels, tire pressure labels, VIN tag and SPID document are all created to match the truck as a result of that process. The build sheet is what communicates to the assembly floor how the truck is to be built.

40 years after the fact: It's a mixed bag. The hardcore restorer will build the truck as originally equipped; some percentage of guys build the truck the way they want. A few will make a new SPID to match the added content; from what I've observed most do not go to that effort*. You probably won't be able to tell unless (a) you have the build sheet or something else documenting the original content or (b) you ask them.

*In reviewing this thread I see one person that made a new SPID to match their added content.

jamesmadconductor, nice looking truck. Does it have Cheyenne emblems?

Canuckvetter, that looks like a 67 GBD by the ridge around the SPID label and the format of the SPID? I could be wrong though.

My '71 also says Custom Sport Truck after the Z84 option. I will reply to this thread with my SPID below.
