I'm just looking at the Fisher body numbers, and the 3 from LA, are DD55LA, DD57LA, and DD59LA. Seems to coincide with the 59 cars mentioned in the Destination list above. The Norwood ones all carry a DDxxD number, how did Norwood become designated as the "D" plant, one would have thought the body tags should have been DDxxN. Cool stuff, note the 283 engines in a couple of the Norwood cars, and the one going to engineering to be shipped in "prime".
So if these cars were being assembled in May of 66, what was Norwood and LA building at that point? Was the plant already in the process of being converted for Camaro production that early (there was still 3 months at least of 66 production time left), or was there just some small parallel assembly line for these 59 cars, or were they hand built in some corner of the plant to bring the senior staff and line personnel up to speed on what was coming?
