Yes - those would be used in addition (as a supplement) to the more familiar build sheet.

The RPO codes alone do not have enough detail to build the truck.

Further detail: let's say you order a 350 cu in engine. There is one base part for a 350, but it proliferates on Auto vs manual trans, a/c vs no a/c and California emissions vs Federal.

So there would be eight part numbers within that one engine family (there would probably be this many variations for v6, for 305 cu in, for 454 cu in and diesel as well):

12345678 350 cu in manual no a/c Fed
12345679 350 cu in manual w a/c Fed
12345680 350 cu in auto no a/c Fed
12345681 350 cu in auto a/c Fed
12345682 350 cu in manual no a/c Calif
12345683 350 cu in manual a/c Calif
12345684 350 cu in auto no a/c Calif
12345685 350 cu in auto a/c Calif

An assembly plant broadcast code would be assigned to each part number:

TAA 12345678 350 cu in manual no a/c Fed
TAB 12345679 350 cu in manual w a/c Fed
TAC 12345680 350 cu in auto no a/c Fed
TAD 12345681 350 cu in auto a/c Fed
TAE 12345682 350 cu in manual no a/c Calif
TAF 12345683 350 cu in manual a/c Calif
TAG 12345684 350 cu in auto no a/c Calif
TAH 12345685 350 cu in auto a/c Calif

So the operator goes over to a bay that is full of racks and racks of engines (probably more than you've ever seen in one place in your entire life). You can tell him which one to choose, via the build manifest, and he can remember that he needs an "AF", instead of trying to remember 123455683, or manual/AC/California emissions, since he will do this nearly 500 times in one day. (Edit 3/9/20201 - and won't remember any of it by the end of the day).

All of the plants used build sheets. The RPO information alone was not enough information for the operator to select the correct part, especially when there was a proliferation of part numbers within the RPO.

Any area where components were built up remotely and then conveyed to the main line in sequence would require a build sheet: front and rear axle trim, engines, transmissions, seats, front end sheetmetal, tire/wheel assemblies, etc. These are all areas with a lot of proliferation, and therefore not easy to present the material lineside, or - in the case of the seat cushions - a fire hazard (the "cushion room" was always way out in the boonies as a result). The build sheet defined the component that was to be installed, by part number or broadcast code, especially for option driven content where there was some choice as to what part was to be installed, or a remote area where there were no visual clues as to what part should be installed. So - theoretically - you would be able to find a build sheet on the motor somewhere, or above the fuel tank, or anywhere a build sheet was used.

There was no thought, guess work, interpretation or latitude on the part of the assembler: they referred to the sheet, selected the component by part number or broadcast code, and put it on.

Ok so I don't have a build sheet in my truck (don't know if the bench seat is original to the truck or not) and I don't' have the little blue sticker but I am hoping that if enough numbers come in I'll be able to get a close guesstimate on when my truck rolled off the assembly line. the partial vin would be 9T800240, all I know is that it is a 1969 c10 that was built in Tarrytown NY and I believe it spent most of it's life in Pennsylvania before I got a hold of it.

Wouldn’t 12/14/67 be a 68? Or was it to be 12/14/66?
