Build dates

One of my '66 Barracudas has an 8/17 production date. In 40 years of looking now, I still haven't seen an earlier one. I wonder how many Barracudas were in the first 500 cars built? It's an original Hawaii car too, with an odd bunch of options. Built in Hamtramck and not LA for some reason. LA wasn't ready yet? Were there different start dates for the plants? Did Hamtramck actually start the next production line exactly on Aug 1st? Same with the LA plant? Seems funny that they would ship a car all the way from Detroit to Hawaii when they have a Ca. plant right near where a car would be loaded on board a ship to be sent out to Hawaii. I figured it was to get the timing right when they announced the new models. They probably wanted all the dealerships to have some cars in stock at the same time, and had to get my Barracuda on it's way to Hawaii in time for that. Probably a showroom car, as it had buffed paint (Z8) according to the fender tag.
Was your car AA-1 Silver?
