Production methods didn't change, the only thing that changed was the body number became tied to the cars order number issued by the central office because of a change in the way the ordering system was handled. The factories no longer assigned body numbers in sequence, the Central Office assigned the order number, and it became the body number. How they made the cars, and what limiting factors affected scheduling at the plants remained the same. If you look at 69 body numbers you can plainly see how they jump around alot more than the 67 and 68 numbers because of the involvement of the central office, and the use of a single set of order numbers. In 67 and 68 you could have a car with the same body number built at LA (LA infact had up to 4 different cars with the same body number in 67) and Norwood (but obviously with different VINs), but in 69 you could not since the central office controlled those numbers instead of each plant.
