COPO disassembly

[Supercar_Kid]

Cool find Al, but I've always been under the impression that a build sheet was being referenced by line workers until a car reached it's final stages of assemby, when sometimes it would be tossed inside the car, glued behind a door panel, tucked under seat springs etc. What seems odd is that it's pretty clear in your pic, that at least this one particular build sheet was actually hog ringed right to the seat springs apparently at the time the seats were covered. Were Chevelle seats actually upholstered at the factory? I always assumed they would have been covered by an outside source and shipped to the assembly lines as complete units ready to install. Apparently that's not the case or your car's build sheet wouldn't have ended up with a hog ring through it. Has anyone else found build sheets in their cars that were hog ringed right to the seat covers like this? Seems odd to me, and definitely interesting to note. Al, have you managed to free it and compare it to your other 2 sheets yet? Post some pics of the info on it when you get a chance. Good luck on the rest of your project.
