A little more information:
I checked the decklid for date codes, and it has a date code that falls in line with the build of the car. That is an old sticker that has not been applied any time recently. And why would someone put a Firebird jack sticker on a Camaro decklid many years after the fact? When people fake things, they try to make them look as close to the norms as possible.
I was looking through my documents and came across the paperwork from when the second owner purchased the car in 1971 from Ellis Brooks Chevrolet in San Francisco. On it is an imprint of the original protecto-plate for the car, showing the correct VIN that matches the car, the assembly date stamp that matches the engine, the exact same date stamp that appears on the transmission, and the rear end stamping. In my mind, this puts this to rest as some type of factory aberration. I think the odds that someone found a Muncie M-20 with the exact same stamp as the protecto-plate, along with a stange VIN that happens to have the Los Angeles "L" in the sequence are extremely slim. If someone stamped the date on the case at a later date, why would the not stamp a matching VIN to the car as well? This date code stamping on the transmission has already been verified as a legitimate stamping.
