Most states have no title records for vehicles titled/registered before 1972 (or even later in some states).
The original-style titles (1948-55) in the four state from which I have seen old titles did not list equipment: make, year, color, body style (maybe GVW) was about it.
The only document (in those years, at least) that might show the configuration of a delivered truck (for example: 5-window option) might have been the sales-slip/contract.
