He believes his is an Oct. build.
I can say for certain that my 08A car did NOT have the mylar vin sticker in the door.
I always thought John Berry's (I believe it has since changed hands) white 08A Z did have the sticker, (the one in Jerry's book). It is less than 100 cars after mine, built the same week. That is why I always believed the practice started first week of August. Not sure who came up with the first week of Sept. as the start date. Normally GM started the next model year in August. That is why the BDY number was reset, to signal the beginning of the models subject to the 70 model year regs. My BDY number indicates it is one of the first 381 cars after the reset.
I had heard there were some other odd issues with the white car (being a 5,000 mile car when Jerry wrote the book) after talking to a fellow who had examined it closely. I had no idea the sticker might be a repro. Are you certain?
One would think Jerry would have caught that at the time.
I spoke with John right after he sold the car, and he certainly didn't indicate there were any repro parts on it.
