What is the difference except for price between the HO camshafts.
Left (2002-2004): P/N 53021411AB
Right (2002-2004): P/N 53021412AB
and the superseded by P/N 53021411AD, superseded by P/N 53021412AD.
I understand that the new models have replaced the old ones but other then the part number is there any actual change?
The reason I am asking is because although they are all on national back-order you can still buy both sets of models from the places that still have some stock left. There is a price difference of around $20-$30 for each pair on the AB vs the AD.
