The only place you will find the regular production options installed on this car is from some original paperwork, its not coded on the trim tags. While some Fisher Body installed options were in the past, GM consolidated assembly operations away from the divisions and placed it under control of one division, GM Assembly Division.
1D - Jan, 4th Production Week of 1970 Production Date (note-Production weeks did not necessarily follow the calendar, it was the weeks the plant was in production. Also, that date was only the week it started which might not be the week it finished as it took roughly 24 man hours (when the plant was working) to build a vehicle from start to finish.
457411 270159 is the Data Processsing Sequence Number (DP SEQ NO found in box 24 on broadcast sheet). It is just a reference number that was generated when the order for this vehicle was entered into the plant computer system. Known as the Broadcast Sytem, it would broadcast all the spec's and parts needed to build this car to all departments in the complex to bring the order together and produce the vehicle. Every computor record has to have a file number and this is it. They put it on the tag because this was a relatively new system (being implimented from 67-70) and the plant workers etc needed to have a way to cross check, especially in the body bank which staged the car for the final lines.
