Build Sheet Thread

[ssbrewskyaz]

Of all the high dollar muscle cars I've restored over the years I've only been fortunate enough a couple of times to find the vehicles build sheet. The build sheet, or in assembly plant terms "broadcast sheet" is the one document that truly details what or what didn't originally come on a car. Essentially, this document was used for the assembly line workers to determine which options the car received. Normally, these manifests are insignificant after a car is produced. Fast forward from 1970 to say, 2010. This is where the broadcast sheet makes a difference.

Let's say there's two identical LS6 Chevelle's at the auction, identical in every detail. They both have the LS6 engine, the M22 transmission, the 4:10 posi rear end, bucket seats, etc. etc.. One car has the build sheet the other does not. Which car is going to bring more money at the auction. Yep, the car that has an undisputable record of the original build detail. These documents can be found glued to door panels, under seat springs front and rear, above the headliner, under the carpet and on some cars, Corvettes particularly, above the fuel tank.

While it's fairly safe to assume our G-Body cars aren't going to skyrocket to the stratosphere in price over the next decades, I thought it would be kinda cool to see the different option content on cars out there in a thread for G-Body build sheets. As is typical for me, all three of my parts cars had the build sheet but the car I'm actually building does not. Go figure. ...

This is a 1980 Malibu Wagon



This is a 1981 Malibu Wagon



This is a 1978 Malibu Sedan (Four Door)

I was able to find the build sheet for the first 79 Camino I bought....on top of the headliner.

Built in Georgia and sent up here...the dealership that sold it is now under new ownership but still there.

Haven't looked through the other two yet.

As Scott mentioned above they can be located in a # of places on the car...I pulled a bunch of mint gray interior parts from an 86 Cutlass and found this one behind the RH side upper door panel...

Ok when I change the window sweeps I'll take a look :!:
Thanks Gbarrie

On my 82 cutlass I found it held with wire clips on the back springs. In my back seat, does anyone have a key or ledgend to decipher these?

We have RPO's (Regular Production Option), not to be confused with SEO's (Special Equipment Option)and not to be left out, we have SPID labels (Service Parts Identification)

Looks like the early broadcast sheets have the RPO and the option description. On the sheet that Kevin posted, it only shows the RPO codes like it does on the current SPID label. I have access to pdf files with the RPO codes but they're pretty large files. I don't really have a way to only display the RPO's that were available on G-Body cars. The files I use are for all of GM including truck and global platforms.

The RPO codes mean relatively the same thing across the car and truck lines. For example, C60 is air conditioning whether it's a Z28 or Silverado Z71. But they do change over the years too. ZL1 in the late 60's was the all aluminum bad boy 427. In the late 80's however it designated a noise abatement package and most currently, in 2012, it represents the high performance Camaro again. If you go to the RPO thread on this site, you'll find a GM RPO index by the alphabet. It's not all inclusive either, for example, when I checked it doesn't reference ZL1 (Aluminum 427) or ZL2 (cowl induction hood). It has the main ones and the rest I can help with. At the end of the day, that's all Z28 is, an RPO, Performance Package, Special, albeit a very important RPO.
