I just completed a buildsheet book for 1973-82 Corvettes and was asked the question about musclecar plants that may have used a similar General Motors Assembly Division manifest...or buildsheet.
I know Chevelles plants in their transition from Chevrolet Motor Division management to GMAD management between 1965 and early 1970s began to use the GMAD manifest but curious about other GM car lines during that period that may have also used this buildsheet format. The format would have been landscape versus either portrait or the envelope size buildsheet I believe I have seen by the Nova group. |

There are recent post, today in this forum on Eaton fan clutches that show other GM build sheet formats.
Question I posed was if those formats were the same as Corvette, can you post the 73 format and do you have formats from earlier years? |

I'm not quite sure I understand what you are looking for - Ditto on posting a sample of what you are after.
I've been with GM in engineering/assembly/new product launch for 34 years so I have a pretty good selection. There is also quite a bit of knowledge surrounding vintage build sheets/manifests useds by Pontiac Motor Division, starting in about 1961 on. Here's a sample of a Pontiac Michigan built car, in 1965: ![]() K

The manifest below is what I am referring to as the GMAD landscape style buildsheet introduced in 1973 at the St Louis assembly plant. These were glued to Corvette gas tanks during chassis buildup.

Not to steal the thread. I have a broadcast sheet on my 69 COPO camaro. The only place on the sheet that shows anything, is in the bottom left of the sheet. By itself, is 9651BA. And my car is a automatic car.BBBenny
