Little bit of a Mopar history question..

So I was researching the history of the Dodge plants in Detroit, and I came up with a question. According to my VIN my '72 Swinger was built in Hamtramck. Now my question is, did Dodge build A bodies in the Dodge Main plant only? I heard somewhere that they owned the old Packard complex for quite a while, and built cars there in the 70's and 80's. Any insight would be pretty helpful, I've been through Allpar and Hamtramck Historical, and neither of them are doing anything but adding to the murky muckiness of this question.

Thanks in advance, Ryan.
