Now, if the rack had all or several of the same trim type seats, the worker would not always grab the exact seat by sequence number. More than likely he just looked at the door panels and grabbed the seat the same trim type as the door panels.

This is correct - as my deuce has the wrong sheet in it, correct only per the interior code.

This style
Fisher Body sheet was replaced by the punch card style that replaced the paper one late in the 1970 model year.

I would say this happened between 06A and 06B of 1970, weeks 2 & 3 respectively of the yenko deuce production run. We have found differences between these two weeks of cars that shows changes were incorporated at this time, ie; 06A and before cars have seat belt retractors, 06B and later do not. Also, the punch card and heavy paper card above the glove box have only been found on 06B cars, not on 06A and before cars.

The Engine codes were dropped in the 1970 model year. If you are looking for proof of a 1970 Big Block car first look for the SS code ZL3. If it was not a SS car it was not a Big Block car.

Was ZL3 an SS designation? I was always curious why GM would put the RPO codes on the sheets for those options requiring body mods, but for the SS mods they would not use 'Z26'

Note: Sequence numbers that were written in crayon and were cleaned off the car by the guy preping the car after it was received at the dealership. The same guy probably threw the GM Body and Chassis Broadcast sheets in the garbage. It was rare that he put these GM sheets in the glove box.

Very true, on many cars the remnants of the sheet can be seen taped to the passenger side of the firewall - sometimes just the tape/glue remains.
Nice explanation
