I've looked under the back seat and above the gas tank and can't find the build sheet. I heard different factories put them in different places, my '70 Chevelle was built in LA. I would appreciate any help.

Most factories put them where they belonged - in the trash. They weren't purposely left in the car to be found 30 years later. Only when the asembly line worker didn't feel like putting them in the trash did they stuff them just about anywhere they could reach when they were done with their portion of the assembly. Under, inside seats, door panels, headliner, kick panels, you name it and build sheets have been found there.

Thanks, I thought the factory was supposed to put then in the car.

Four or five gallons of gas were pumped into the tank, the carburetor was primed by filling the float bowl through the vent tube, and the car was started for the first time; idle speed was adjusted, automatic transmissions were topped-off, the air cleaner was installed, and the car was ready for drive-off. The Scheduling clerk had already produced the P-O-P from the Broadcast Copies picked up at the Engine and Chassis lines, the window sticker, car shipper, and final order copy had been produced, and these were placed in the glove box with the warranty folder and owner's manual while the window sticker was applied to the door glass. The car was then "de-papered" by removing all the extra Broadcast Copies, supplier labels, etc. that were taped all over the car as assembly information, and trashing them. Each car and its scheduled subassemblies picked up about twenty Broadcast Copies at it progressed through the Chevrolet assembly system, but it was strictly an internal plant information document and none were shipped with the car's paperwork package to the dealer.

Hi, I found mine inside the back of the front seat. I would check both seat backs if you are going to redo your seats.Ray

My Van Nuys built '70 had one on top of the gas tank. The car is completely disassembled and that is the only one I found. The car was built December of '69. I think it was pretty common for Van Nuys to put them on top of the tank. Since your car was built there and you already checked, you may be out of luck.
