1963 data plate info

The tags for 65 and earlier didn't follow the pattern as it did the 66 and up tags. The nice thing on the early cars (67 and earlier) is that you can get the build card from Chrysler historical.

Really? How would one go about doing that? And is there any info at all out there for deciding the 1963 data plates? I have 1 hamtramick car and 1 LA car. I do recall the different factories using different data plate methods. Thanks. Eric L
