Case75 said You also get a package of all the engineering specs on your particular year.
You used to be able to get that "package" with the "Restoration" package from GM years ago. I got one for my '74 waaaay back, right after I bought it. They don't do that anymore....at least not for free, like it was then. The nest year, when I tried to get the same deal on my '85, all I got was aboot 10 copies of the build sheet....nothing else.
GM Canada has always been good about retaining records....thumbs up to the Canucks for that, at least!
