That is part of why I loved my 97 even in as bad of shape as it was, it was as old as me. Idk if this helps, but this sticker along with some interior trim panels told me the vehicle had an earliest start build date around middle or end of november, and it was completed before christmas. I was completed dec. 6.
If you don't have the sticker on the door anymore as they often peel, take off the top dash trim piece. That will give you a rough idea but not sure about finding out the exact day it was finished. That was always something I was curious about.
