1968 Baracuda Convertible - trunk lip stamping numbers

"1968 had unique body codes...Assembly plant,Model year, 1st digit of VIN, and Sales Order Number...ie: B8X XXXXXX."

I wonder if there is a source that can use that data to get more information on the original vehicle. Seems a sales order number could be backtracked to the actual sales order and all the data it might contain.
