I don't know if I am interpreting the diagrams correctly.

Are these diagrams saying that there was a part that was updated on 10/2003 production? The updated part for the 2003 model-year car is different part number from the one that was on the 2004 model year car. So is that saying the updated driveshaft for pre-LCI cars will NOT fit on LCI cars?
